Quick answers to common questions about 21bitcoin

21bitcoin is a Bitcoin-only app designed for secure, low-cost, and fast Bitcoin transactions . It is ideal for users seeking transparency, with competitive fees from 0.79%, no deposit fees, and 24/7 support
At 21bitcoin, we don't charge any deposit fees - depositing is always free of charge.
Fees for buying Bitcoin start at just 0.79% - 21bitcoin always offers fair and transparent pricing.
We offer top rates and charge a flat fee of only ~ EUR 1.00 per transaction.

Every exchange worldwide has its own Bitcoin price because it has its own buyers and sellers who set their own prices. The Bitcoin price is therefore determined by supply and demand on each individual marketplace.


As a result, there is no single official Bitcoin price, but rather many market prices that are constantly adjusting to each other, similar to currency exchange rates. Since supply and demand are constantly changing, the Bitcoin price can fluctuate within seconds.


To ensure that you can still buy safely and reliably, we guarantee the price displayed for 20 seconds - even if the market moves during this time.


To make this price guarantee possible, the displayed price includes a small safety margin (price range). This price range is already transparently included in the price on the confirmation screen in the preview.


The price range serves to cushion short-term market fluctuations and offer you a stable, guaranteed price - without the risk of the price suddenly changing in those crucial seconds.

21bitcoin is a decentralized protocol with audited smart contracts. Your funds remain in your wallet until you execute a trade. However, always do your own research, use secure wallets, enable all security features, and never share your private keys.
At 21bitcoin, your Bitcoin are secured by cold storage technology and backed by a $250 million insurance policy from our partner BitGo Custody.
