Why buying BOOKUSD in a non-custodial wallet is safer
When you buy BOOKUSD on an exchange, the exchange holds your funds. If the exchange is hacked, freezes withdrawals, or goes bankrupt, your BOOKUSD is at risk. Tangem ensures that doesn't happen to you. When you buy BOOKUSD, our integrated provider sends it directly to your wallet's public address.
