Recurring buy

Think of it as a standing instruction rather than a strategy. River makes recurring orders zero fee once the schedule has been running seven days, Swan built an entire product around them at about 0.99 percent, and Coinbase runs them through the same simple-buy pricing as a one-off tap. Which button you use decides whether the schedule is cheap or expensive.

How it works

Setting up a recurring buy takes four choices: an amount, a currency, an interval, and a funding source.

On the trigger date the platform debits your chosen rail and buys at whatever price the venue is quoting at that moment. You do not select an order type and you cannot name a price, which is the trade you are making for not having to show up. On broker-style platforms the fill is the broker's quote including its spread; on order-book platforms the schedule usually fires a market order.

Settlement timing is the detail most people miss. A bank debit over ACH or SEPA does not clear instantly, so platforms handle the gap in one of two ways. Some credit the bitcoin immediately at the schedule-day price and lock withdrawals until the money arrives, typically a few business days. Others wait for the funds and buy at the settlement-day price, which means the price you get is not the price on the day you chose. Read which one your platform does before assuming your average cost matches the chart.

Failures are silent. An expired card, a changed account number, or an insufficient balance skips the cycle, and most platforms notify by email only. Check the order history quarterly, because a plan that stopped in March is not a plan.

River's structure is worth knowing in detail because it is unusual: the zero-fee rate applies from seven days after the order is created, so the first order pays the standard tiered rate of up to 1.2 percent and, on a daily schedule, so does the first week.

Where you see it

Recurring buys now appear on bitcoin-only brokers, large exchanges, and payment apps, and the pricing varies more than the feature does.

The trap is the interface it runs through. On several large exchanges, the recurring purchase is a function of the simple buy screen rather than the professional order book, so the schedule permanently inherits the more expensive pricing even though the same account can trade at published maker and taker rates. If your platform splits its products this way, a manual limit order on payday can cost a fraction of the automated version.

Funding rail matters just as much. Card-funded schedules stack a processing surcharge on every cycle, while bank transfer rails are the cheap ones. Relai runs entirely on SEPA and SEPA Instant for this reason, and most European platforms make SEPA deposits free while charging for cards.

The last feature worth switching on is automatic withdrawal. River and Swan can push accumulated coins to an address you control on a threshold or a schedule, which converts a growing custodial balance into coins you actually hold. Without it, a recurring buy is an automated way to build a bigger position at a company you have never audited.
