I ve read that some e-wallets restrict your account and ask for ID docs to unblock access to your funds (coinbase).
So, some people say that they don't leave their btc in wallets for long time, as soon they get BTC funds they exchange for FIATS and this is more secure.
I do not know much about fiats and all.
Can you point to a good tutorial or guide on how to do that? or share some lights to use BTC to keep they safe or a good site to exchange them for USD , like using Paypal as conversor?
Or any secure e-wallet that dont's ask for ID proof?
Coinbase isn't actually a web wallet but an exchange wallet that's why there are instances on where wallets have been blocked.You can actually use lots of different wallet its either on web wallet or hardware or pc wallets it does depends on your choice but if you are really concern about security of your bitcoin then store it on hardware wallets because it much safer as long you do keep safely its private keys and with that no one could able to take away your bitcoins from you.
