We recommend that you hold onto your own bitcoin private keys. In order to do so, you must have a wallet, either on your phone or desktop or generated through a hardware wallet.
For your mobile and desktop needs, we have compiled a list of wallets we recommend: https://veriphi.io/en/blog/wallets-analysis-update
We have also compared the Coldcard, Trezor and Ledger hardware wallets: https://veriphi.io/en/blog/comparison-of-coldcard-trezor-ledger
For more users seeking a more advanced and secure bitcoin storage setup, we have also created a multisignature scheme tutorial, found here https://veriphi.io/en/blog/coldcard-multisig-tutorial
You can always contact us if you’d like additional assistance or a more advanced or custom setup.
