## 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, and it charges 0% ChainATM fees on USDC and EURC. ChainATM is non-custodial throughout: it never holds your funds, and purchases are executed by Coinbase straight into a wallet you control.

### What does BISON cost compared to ChainATM?

BISON: Spread-based pricing rather than a separate stated commission. ChainATM: 1 credit per transaction, from EUR 0.099 per credit, and 0% ChainATM fees on purchases of USDC and EURC. Other tokens use standard Coinbase on-ramp pricing. Network gas fees apply on both sides and go to the blockchain, not to the provider.

### 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, or fee-free USDC and EURC purchases.

### 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. The fiat on-ramp runs through Coinbase, with EUR purchases by SEPA, card and Apple Pay.
