Our take
bity
Bity provides a non-custodial fiat gateway and crypto brokerage established in Neuchâtel, Switzerland. Operating since 2014, the service connects European banking rails including SEPA and Swiss domestic transfers directly to on-chain cryptocurrency deliveries. Unlike centralized trading hubs that hold account balances on centralized ledgers, Bity functions as a direct execution intermediary. Purchased assets settle immediately into personal self-custody addresses, while crypto sales convert into bank payouts or physical cash through its regional ATM network.
This operational architecture eliminates counterparty insolvency custody exposure, appealing directly to users who prioritize wallet autonomy and Swiss regulatory standards. The tradeoff emerges in transaction costs, as integrated broker fees and network mining charges exceed standard maker and taker tiers on deep order books. For retail buyers and institutional clients demanding direct on-ramp execution without exchange-side asset custody, Bity delivers a focused and transparent Swiss service.
Coldcard
Coldcard, developed by Canadian hardware security manufacturer Coinkite, provides an uncompromising approach to Bitcoin self-custody. By deliberately restricting firmware scope to Bitcoin, Coldcard minimizes attack surfaces while introducing advanced defensive controls. It separates the signing environment from internet-connected computers through MicroSD or optional near-field communication workflows, allowing transaction signing without exposing private keys to local operating system vulnerabilities.
The device is built for disciplined custody architectures, integrating dual secure elements, duress PINs, brick-me PINs, and native multisignature descriptor coordination. However, this rigorous design requires operational comfort with third-party coordinators like Sparrow or Electrum. Coldcard represents an exceptional choice for disciplined Bitcoin storage, though users wanting multi-currency support or simple touch-and-go interfaces will find its technical depth challenging.
