IDR vs USDT Trading Pair: Key Differences and Which Is Better?

When buying Bitcoin or other crypto assets, Indonesian traders usually encounter two options.market, namelypair IDR And USDT pair. 

The assets being traded can be the same, but the price,costs, liquidity, and even the final results are not necessarily identical.

For example, Bitcoin It can be traded via BTC/IDR or BTC/USDT. In BTC/IDR, Bitcoin prices are expressed in Rupiah.

Meanwhile, in BTC/USDT, the Bitcoin price is calculated using Tether or USDT, a stablecoin designed to follow the value of the United States dollar.

These differences raise the question:Trading using IDR or USDT, which is more profitable?

The answer cannot be determined solely from the currency used.

The best pair depends on order book liquidity, spread, conversion costs, USD/IDR exchange rate movements, the asset being traded, and the trader's needs after closing the position.

Key Takeaways

• IDR pairs are more practical for beginnersbecause the price is directly in rupiah anddoes not require additional conversion to USDT.

• USDT pairs usually offer a wider selection of assetsand more frequently usedfor active trading in global markets.

• Profit is not determined by the type of pair alone, but also influenced by spread, liquidity,transaction fees, slippage, and changes in the USDT exchange rate against the rupiah.

What is IDR Trading Pair?

IDR trading pair is a trading pair that uses the rupiah as a comparative asset orquote assetSome examples are:

• BTC/IDR;

• ETH/IDR;

• SOL/IDR;

• XRP/IDR;

• USDT/IDR.

In the BTC/IDR pair, the number displayed indicates the amount of rupiah needed to buy one BTC. If BTC/IDR is at Rp1.2 billion, it means one Bitcoin is trading at around Rp1.2 billion in that market.

IDR pairs are widely used on local exchanges because users can buy assets using rupiah balances and sell them back directly to rupiah.

This path is relatively easy for beginners to understand because it does not require converting the value from dollars or stablecoins.

What is a USDT Trading Pair?

USDT trading pairs are trading pairs that use USDT as the benchmark asset. Examples include:

• BTC/USDT;

• ETH/USDT;

• SOL/USDT;

• DOGE/USDT.

USDT is a cryptocurrency issued by Tether and is designed to mirror the US dollar at a one-to-one ratio. Tether claims its tokens are backed by reserves and regularly publishes reserve reports. 

However, USDT remains a digital asset issued by a private company, not an official dollar issued by the United States government.

Due to its widespread use on various international exchanges, USDT is often used as an intermediary asset to move from one crypto to another without first transferring funds to a bank account.

Why Are BTC/IDR and BTC/USDT Prices Different?

Source: AI

Bitcoin prices in the IDR and USDT markets should have relatively close economic values ​​after accounting for exchange rates. Simply put, the relationship between the two can be described by the formula:

BTC/IDR Price ≈ BTC/USDT Price × USDT/IDR Price

For example:

• BTC/USDT: 70,000 USDT;

• USDT/IDR: Rp18,000;

• BTC/IDR estimate: 70,000 × Rp18,000 = Rp1.26 billion.

However, the actual BTC/IDR price may be slightly higher or lower than these results. Price differences may arise due to order book conditions, transaction volume, local user demand, spreads, arbitrage delays, and changes in the USD/IDR exchange rate.

Some sites explains that the USDT market is more closely linked to global trade flows, while the IDR pair is influenced by local liquidity flows.

Both markets usually move in the same direction, but do not necessarily show the same price every second.

Converter 1 USDT to IDR

1. Difference between demand and supply

The price of each pair is determined by buy and sell orders in that market. If demand for Bitcoin in the IDR pair increases while sellers are limited, the BTC/IDR price may trade at a premium to the global price.

Conversely, significant selling pressure in the local market could cause the BTC/IDR price to temporarily fall below the BTC/USDT conversion rate.

2. Changes in the price of USDT against the rupiah

While USDT is pegged to the value of one US dollar, the price of USDT in Indonesian Rupiah can fluctuate depending on the dollar exchange rate, local demand, and liquidity conditions.

When the rupiah weakens against the dollar, the USDT/IDR price tends to rise. Consequently, BTC/IDR can rise even if the BTC/USDT price remains unchanged.

3. Spread and order book depth

The spread is the difference between the highest buy price and the lowest sell price. Pairs with high volumes don't necessarily have the tightest spreads if available orders near the market price are relatively few.

Therefore, traders should not only compare 24-hour volume. They should also examine:

• the distance between the bid and ask prices;

• number of orders at several price levels;

• slippage estimation;

• transaction frequency;

• the size of the position to be executed.

4. Arbitration does not take place immediately

Arbitrage traders typically exploit price differences between pairs or exchanges. This activity helps bring the BTC/IDR price closer to the BTC/USDT value after conversion.

However, arbitrage is time-consuming and costly. Differences in deposit and withdrawal processes, blockchain networks, transfer limits, and liquidity can cause price differences to persist longer during market volatility.

IDR vs USDT Transaction Fees

Cost is one of the most important factors when choosing a trading pair. A pair with a seemingly more favorable price movement may not necessarily yield a higher net profit after all costs are taken into account.

Cost components that need to be examined include:

Maker and taker fees

A maker is a trader who places a limit order and adds liquidity to the order book. A taker is a trader who takes an existing order, for example through a market order.

Taker fees are usually equal to or higher than maker fees. The amount depends on the exchange's policies and user level.

Taxes and administration fees

The fee structure of IDR and USDT pairs can differ even if they are traded on the same exchange.

For example, Ajaib's fees page, effective August 1, 2025, shows the difference in tax and SRO fees between IDR and USDT pair transactions.

On that page, purchases via IDR pairs have lower tax and SRO components than purchases via USDT pairs. Selling transactions also have their own calculations.

Meanwhile, the some exchanges fees page explains that crypto asset purchases are no longer subject to VAT, and sales are subject to income tax in accordance with PMK Number 50 of 2025.

Rupiah deposit, withdrawal, and digital asset transfer fees may also vary based on the payment method or network used.

Rates are subject to change.

Therefore, traders need to check the latest fees page on the exchange before making a transaction.

IDR to USDT conversion fee

If the initial capital is in rupiah but the asset you wish to purchase is only available in USDT pairs, traders need to make two transactions:

IDR → USDT → asset crypto

When an asset is sold and the funds are to be disbursed to a bank account, the process can be:

crypto asset → USDT → IDR

Each level has the potential to give rise to:

• trading costs;

• spread;

• slippage;

• SRO taxes or fees;

• USDT/IDR price changes.

Therefore, comparing costs isn't just about looking at the maker or taker percentage. Consider the entire transaction path from initial capital to the return of funds to rupiah.

USDT transfer fees

USDT can be sent across multiple blockchain networks. Withdrawal fees vary depending on the chosen network and exchange policies.

The network selection must also match the recipient's address.

Sending USDT over an unsupported network may result in assets being difficult or even impossible to recover.

Liquidity of IDR Pair Compared to USDT

Globally, USDT pairs are generally available on more exchanges and are used to trade a wider range of assets. USDT is also often the primary pairing for Bitcoin, Ethereum, altcoins, and new tokens.

However, this does not mean that all USDT pairs are necessarily more liquid than IDR pairs.

On Indonesian exchanges, IDR pairs for major assets like BTC, ETH, USDT, XRP, or SOL can experience high trading activity. USDT pairs for less popular assets can have thinner order books.

Liquidity should be assessed per pair and per exchange. Indicators that can be used include:

1. 24-hour trading volume, to view transaction activity.

2. Bid-ask spread, to measure the difference between buying and selling prices.

3. Market depth, to see the number of orders at several price levels.

4. Slippage, to estimate price changes due to order size.

5. Execution speed, especially when the market is moving fast.

Pairs with high liquidity typically offer tighter spreads and lower slippage. This is important for active traders who frequently open and close positions.

Is the Profit Pair USDT Greater than IDR?

Using USDT doesn't automatically result in greater profits. Similarly, using IDR pairs doesn't necessarily mean lower profit potential.

Profit is influenced by:

• entry price;

• exit price;

• position size;

• transaction fees;

• spread;

• slippage;

• exchange rate changes;

• risk management strategy.

Some also emphasizes that trading results are determined more by entry and exit strategies, fees, spreads, and liquidity than simply choosing between USDT and IDR.

Example of the effect of exchange rates on profits

Suppose a trader buys BTC when:

• BTC/USDT: 70,000 USDT;

• USDT/IDR: Rp16,000;

• BTC/IDR value: around Rp1.12 billion.

Then, the BTC price rose 5% to 73,500 USDT. At the same time, the rupiah weakened 2%, bringing the USDT/IDR exchange rate to Rp16,320.

The BTC value in rupiah is:

73.500 × Rp16.320 = Rp1.199.520.000

Compared to the initial value of IDR 1.12 billion, the increase is around 7.1% before costs.

The BTC price in dollars only rose 5%, but the yield in rupiah was higher due to the additional influence of the weakening rupiah.

Conversely, if the rupiah strengthens, the increase in BTC/USDT may appear smaller when calculated in IDR. This means that traders trading IDR pairs are exposed not only to crypto asset movements but also to the rupiah's value against the dollar.

Advantages of Trading Using IDR Pair

IDR pairs are generally more suitable for users who receive income, save, and calculate financial needs in Rupiah.

Its advantages include:

• prices are easier to understand;

• capital can be used directly without purchasing USDT;

• simpler disbursement of results;

• fewer transaction stages;

• makes it easier to record investment values ​​in rupiah;

• suitable for recurring purchases or dollar cost averaging;

• reduce the risk of holding stablecoins in the long term.

IDR pairs can also be more efficient if the trader's ultimate goal is to withdraw funds to an Indonesian bank account.

USDT Pair Profit

USDT pairs are more suitable for traders who need flexibility and access to a global trading ecosystem.

Its advantages include:

• available on many exchanges;

• asset choices are usually wider;

• facilitates price comparisons between platforms;

• can be used as a waiting balance after selling assets;

• facilitate the transfer of capital between pairs;

• frequently used in spot trading, futures, bots, and arbitrage strategies;

• reducing the need to constantly go out to a bank account.

However, storing USDT carries additional risks. Although designed to be stable against the dollar, USDT's market price is subject to small fluctuations. Users also face risks related to the issuer, platform, blockchain network, wallet security, and the possibility of depreciation.

Which is Better for Beginners?

For Indonesian beginners, IDR pairs are usually easier to use because prices are directly quoted in rupiah. Capital can be deposited via bank transfer, used to purchase assets, and then withdrawn without additional conversion.

Ajaib also considers the IDR market easier to understand for beginners because it uses local currency and offers a more direct transaction route.

However, beginners still need to learn the USDT pair if they want to:

• buy assets that do not have an IDR pair;

• using international exchange;

• compare global prices;

• transact more actively;

• using derivative products;

• transfer balances between pairs.

A sensible approach is to start with the IDR pair to understand the order book, limit orders, market orders, spreads, and fees. After that, users can gradually learn the USDT pair.

• You use Indonesian exchange;

• want to purchase large assets periodically;

• want to store temporary balances in stablecoins;

How to Choose IDR and USDT Trading Pairs

Use the following steps before placing an order:

1. Determine whether the final result is to be stored in crypto, USDT, or rupiah.

2. Compare asset prices after conversion using USDT/IDR rates.

3. Check the spread and order book depth of both pairs.

4. Calculate maker or taker fees.

5. Enter the IDR to USDT conversion fee if required.

6. Consider taxes, SRO fees, and withdrawal fees.

7. Estimate slippage based on transaction size.

8. Avoid changing pairs just because you see a difference in the nominal price.

9. Use a crypto asset exchange with a license and operational status that can be verified through the Financial Services Authority (OJK). Regulation and oversight of digital financial asset trading in Indonesia falls under the OJK, with provisions updated through POJK No. 23 of 2025 and its implementing regulations.

Conclusion

The main differences between IDR and USDT pairs lie in the underlying assets, trading ecosystem, exchange rate risk, conversion fees, and access to crypto assets.

The IDR pair is simpler for Indonesian users because prices are directly quoted in rupiah, and funds can be transferred to a bank account with fewer steps. The USDT pair offers a wider selection of assets, access to global markets, and flexibility for active traders.

BTC/IDR and BTC/USDT prices may differ due to changes in the USDT/IDR exchange rate, order book conditions, spreads, local demand, and arbitrage speed. 

These price differences do not automatically translate into profit opportunities, as traders must still consider costs, slippage, and the risk of price fluctuations during the transaction process.

For beginners, the IDR pair is generally an easier starting point. For active traders who frequently switch assets or use multiple exchanges, the USDT pair can be more efficient. The best choice is a pair with adequate liquidity, tight spreads, low total costs, and a fit for the intended use of the funds.

Is trading with USDT more profitable?

Not automatic. Fixed profits depend on entry and exit prices, fees, spreads, slippage, exchange rates, and trading strategy.

No. USDT pairs typically have wider global reach, but actual liquidity should be checked on each asset and exchange. IDR pairs for popular assets may have better liquidity than certain USDT pairs.

Prices may appear higher due to rupiah depreciation, local premiums, spreads, or high demand in the IDR order book. Compare prices after multiplying the USDT pair by the USDT/IDR price.

Not when the exchange provides BTC/IDR. USDT is required when the asset is only available in USDT pairs or when the trader chooses to use the USDT market.

Which one is suitable for long term investment?

The IDR pair can be more practical for investors saving and evaluating portfolios in rupiah. The USDT pair can be chosen if liquidity is better or investors want to maintain some funds pegged to the dollar. The decision still needs to consider stablecoin risks and financial goals.
