Binance.US or River? How to Calculate the Cost of Buying BTC Weekly

Binance

29 October 2026

The cost of buying BTC every week depends on whether you choose Binance.US for instant manual purchases or River for scheduled recurring buys. If you buy a fixed amount weekly and use automatic bank account deductions, River can offer zero fees after you set up recurring purchases, making it the cheaper long-term path. But if you need instant execution, or your purchase amount is too small to justify waiting for the deduction cycle, Binance.US has an extremely low cost structure of 0% Maker / 0.02% Taker for manual buys, with no fee threshold like River's first 7 days of recurring purchases. Both platforms are not suitable for non-US residents, and this is a more fundamental deciding factor than the fee difference.

Binance.US Current Actual Fees

Binance.US unified its spot trading fees across the entire platform to 0% Maker / 0.02% Taker in April 2026, eliminating the previous complex tiered structure based on trading volume. Its official fee page currently shows: except for the BNB/USD Tier 0 trading pair which has 0% Maker / 0.01% Taker, all other trading pairs are 0% Maker / 0.02% Taker. You can get an additional 50% discount by paying fees with BNB, but you need to hold BNB and enable the corresponding setting. If your BNB balance is insufficient at the time of deduction, the discount will not apply.

When buying BTC weekly, if you use a market order or simply click "Buy," your execution type is essentially Taker, and the cost is 0.02%. Buying $100 worth, the fee is about $0.02. If you place a limit order and the order waits on the order book to be filled, you become the Maker and the fee is 0. But in a weekly dollar-cost averaging scenario, most people won't watch the market and place limit orders just to save 0.02%, so the actual cost of manual buying is that 0.02%.

Binance.US offers free ACH bank transfers for both deposits and withdrawals, meaning there is zero friction cost for moving funds in and out, which is friendly for small weekly purchases.

River's Zero Fees Have Clear Conditions

River is a US-based platform that only deals with Bitcoin. Its one-time manual purchase fee is 1%, which is significantly higher than Binance.US. But River's core selling point is that recurring buys are zero-fee once conditions are met.

Zero fees do not apply from the first order. According to River's official help page: Daily or hourly recurring purchases become zero-fee starting from day 8; weekly, bi-weekly, monthly, and other frequencies become zero-fee starting from the second order. This means if you set up weekly purchases, fees still apply to the first week, and zero fees start from the second week. If you set up daily purchases, there are fees for the first seven days, and zero fees starting from day 8.

River's recurring purchases support deductions from a linked bank account, with minimum amounts varying by frequency: a minimum of $1 for daily and $10 for weekly (bank account deduction). For a weekly buying scenario, you need at least $10 per week to set up recurring purchases with a bank account.

There is one easily overlooked detail: River's bank account deduction schedule. If you set up daily recurring purchases with bank account deductions, River does not deduct once per day. Instead, it deducts the total amount for the next seven days at the beginning of each week. Weekly purchases are deducted 1 to 3 business days after the transaction, which is relatively straightforward.

Calculating Costs Side by Side

Assume you buy $100 worth of BTC every week for one year, using a bank account.

Binance.US: Each manual market buy incurs a 0.02% Taker fee. The weekly fee is $0.02, totaling about $1.04 for 52 weeks. If you are patient enough to place limit orders that fill as Maker, the cost is zero, but this is not the typical operation for weekly dollar-cost averaging. ACH deposits are free, with no additional friction.

River: Set up weekly recurring purchases. The first order has a fee (estimated at 1%, but the official page does not separately list whether the first recurring purchase rate is exactly 1% in the recurring buy description; this uses the platform's published one-time purchase fee as a reference), and zero fees apply from the second order onward. Out of 52 orders in the first year, the first order may cost about $1, and orders 2 through 52 are zero. The total fee is about $1, almost the same as Binance.US's $1.04 for manual buying. But if you extend the timeframe to two or three years, River's zero-fee advantage becomes apparent: Binance.US charges that $1 every year, while River only has a cost on the first order.

If the weekly amount is smaller, say $20, Binance.US charges $0.004 per Taker trade, about $0.21 per year. River's $20 weekly amount meets the $10 bank account minimum; the first order fee at 1% is about $0.2, and zero fees after that. The difference between the two is very small in absolute terms. What really widens the gap is when the amount gets larger: at $500 per week, Binance.US charges about $5.2 in Taker fees per year. River is zero-fee from the second order onward, with the first order estimated at $5 at 1%, so the total first-year cost is about $5, and zero every year after that.

Who Is Each Platform Better For?

If your need is "set up automatic deductions, never manually operate again, and hold BTC long-term", River's zero-fee recurring purchase structure is more suitable. What you sacrifice is the low fee rate for one-time manual purchases (1% is expensive for manual buying), but what you gain is zero marginal cost once you enter the recurring purchase track. You need to accept the first-order or first-seven-days fee threshold, and the fact that River only deals with Bitcoin and no other cryptocurrencies.

If your need is "manually buy once a week, occasionally adjust the amount, and not be tied to a deduction cycle", Binance.US is more straightforward. The 0.02% Taker cost is extremely low, ACH is free, and there is no first-order fee threshold. What you sacrifice is the possibility of "absolute zero fees" (unless you place Maker orders), as well as Binance.US's historical record of regulatory turbulence in the US. This is not a fee issue, but it is background you should know when choosing a platform.

If you are not in the United States, direct registration and use of either platform is not applicable. Binance.US is a US entity serving US users; River's availability is also based on US states. Just because a webpage loads does not mean you can complete identity verification and deposit funds.

Additional Things to Note

River's 1% one-time purchase fee is data listed on Bitbo's comparison page. River's official help page mainly emphasizes zero fees for recurring purchases and does not directly confirm the current official one-time purchase rate in the search results. If you plan to make manual purchases on River rather than recurring purchases, refer to the quote displayed in the interface after logging in. Binance.US's 0.02% Taker fee is clearly listed on its official fee page, and that page's current display should be your reference.

Both platforms' fees may change. Binance.US just made a platform-wide adjustment in April 2026, and River's zero-fee policy is also premised on "meeting conditions." Before setting up recurring purchases, checking the actual deduction amount on the confirmation page is more reliable than memorizing a specific number.
