I'm very new with cryptos and wanna ask, is safe to store all your cryptos in a universal wallet like coinbase? thx!
Just to be clear..Coinbase is not a wallet, it's an exchange that has its own wallet..they may take all your coins and run away..of course Coinbase is probably trustworthy, but they may get hacked for example like we hear very often with other exchanges. Best thing is to keep the coins you are not actively trading in a wallet (hardware, software, paper)..and the ones you trade more often, you could leave them on exchanges.
