Hello,
i don't know bitcoin very well but i have money in btc on coinbase. I am not sure have money on coinbase is very secure. What do you think about it ? Is there a way for have bitcoin with security because i scared coinbase block my account or give information on how much money i have on it, i think it is not very anonymous
I would suggest that you should take it out of Coinbase and deposit them instead in a more-decentralized trustless Bitcoin wallet like Trust Wallet, Blockchain Wallet, or buying a Ledger Nano S. As the old man said, “Not your keys, not your coins”.
If you want them to be more secured than ever, you should keep your Bitcoin where you control the private key or mnemonic phrase.
