As the title says, where can I store my btc safely? Like a cold storage or something, but i dont get the idea of it... Also when it is safe, I want to deposit to it, is that possible?
Definitely Coinbase. I've been using it for a year or so now and have no problem with it.
It's secure and very easy to use. Has "My Vault" aside from "My Wallet" for safer storage.
