Fair enough. A transaction is secure, but the wallets might not be. If you rely on a 3rd party to host your wallet (ie, Coinbase), then you risk your money being stolen when they get hacked. If you host it yourself, then you risk losing the keys unless you make a backup, and the backup could get lost, or if you store it in cloud storage, it could get stolen there. Credit cards are harder to secure than wallets IMO, but at least with CCs, you have recourse in the case of fraud.
