Now I only use Trustwallet to store Bitcoin I have. Am I in the right type of wallet to store my Bitcoin?
Trust wallet is a non custodial but closed source wallet, that alone does not makes it a perfect choice, if it was then an open source non custodial wallet, then we could have seen it as a kind of perfect choice, all i will give you is to choose any wallet that is under a cold storage category because they are non custodial wallet.
Honestly, after reading the article I was confused af, need some good input & insight from experts here.
