ChainATM vs BISON
How does ChainATM compare to centralized crypto exchanges? Here's an honest side-by-side.
What BISON is
BISON is a German crypto trading app from Boerse Stuttgart Digital, aimed at beginners, with German banking rails and German-language support.
The structural difference is custody. BISON holds your crypto until you withdraw it, which is what makes its trading features possible and also what puts your balance on someone else's books. ChainATM delivers to a wallet you hold the keys to, so there is no withdrawal step, and no one to ask if you want your funds moved.
Common questions
Is BISON or ChainATM better for buying and sending crypto?
It depends on which part you do most. Pick BISON if what your use case turns on is what it is strongest at: Backed by Boerse Stuttgart, a German exchange operator; Very low friction for German beginners. ChainATM is the better choice if you want to buy, swap and send from one conversation instead of three separate flows. ChainATM adds no fee or markup of its own. Network, provider and bridge costs still apply. Some are built into the quoted amount rather than listed separately, so check what you pay and what you receive before you confirm. ChainATM does not operate an omnibus customer wallet or hold crypto on its own balance sheet. The default embedded wallet is provided by Privy. After you confirm a supported action, execution may use ChainATM's authenticated backend and Privy's wallet infrastructure, or request approval from a connected external wallet, depending on the route. A card or bank purchase is processed by the third-party provider shown in the app.
What does BISON cost compared to ChainATM?
BISON: Spread-based pricing rather than a separate stated commission. ChainATM: each message you send to the AI in chat uses 1 credit (from about EUR 0.08 per credit with the 500-credit pack), and a buy, swap or send itself uses no credits. ChainATM adds no fee or markup of its own. Network, provider and bridge costs still apply. Some are built into the quoted amount rather than listed separately, so check what you pay and what you receive before you confirm.
Can I use BISON and ChainATM together?
Yes. ChainATM is self-custody and does not require you to move away from BISON. Many people keep BISON and use ChainATM for the parts that are awkward elsewhere: cross-chain swaps in a single command.
Does ChainATM hold my crypto like BISON does?
No. BISON holds your crypto on its own books until you withdraw it. ChainATM is non-custodial: the coins land in your own wallet, we never hold your funds, and we never have access to your keys in usable form. There is no withdrawal step, because nobody else held the funds in the first place.
Is ChainATM available in my country?
Availability depends on our on-ramp partners' supported regions. ChainATM is built by Noctra Labs UG (haftungsbeschränkt) in Trier, Germany, registered at Amtsgericht Wittlich under HRB 48033. Card or bank purchases run through a third-party provider shown in the app; payment methods depend on that provider and your region.

When ChainATM is the better choice
ChainATM is the better fit if you want the crypto in your own wallet from the moment you buy it, and if a chat is a more natural interface for you than an order book. It is not a trading terminal and does not try to be.
Why Choose ChainATM Over BISON?
Self-custody by default
BISON's exchange is custodial: you deposit funds, they hold them, you withdraw later. ChainATM is self-custody. Crypto goes directly to a wallet you control.
No order books, no jargon
BISON's consumer interface is still a trading product with charts, pairs, and forms. ChainATM is a chat: "Buy $100 of ETH" and that's the whole interaction.
One app for buy, swap, send
BISON splits buying, trading, and sending across multiple flows. ChainATM is one conversation.
Voice on iOS
BISON has no voice interface. ChainATM lets you buy, swap, and send by speaking on iOS.
