21bitcoin

21bitcoin is a Bitcoin-only app for buying and regularly accumulating BTC with euros. The product is aimed at retail users who want a simple way to build a position over time, though a separate over-the-counter route exists for larger tickets.

Buying options The website presents recurring purchases through Auto-Invest, as well as instant buys and limit orders. Only BTC is offered, and the listed fiat currency is EUR.

Fees The company publishes a fee schedule. Auto-Invest is stated to cost 0% from the eighth day of a plan. An instant buy is priced at 1.29% to 1.49%, and a limit order at 1.49%. For OTC trades starting at 100,000 EUR the stated rate is 0.49% to 0.99%.

Who it suits The service fits individuals who prefer scheduled savings in a single asset rather than a multi-coin exchange. Larger buyers can use the OTC tier. Regulatory status, supported countries and payment methods are not detailed in the available description and should be confirmed with 21bitcoin before use.
