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
If you use coinbase mainly to store your bitcoins you can just use every security offers that coinbase provides. It's not really a smart move to store bitcoins regularly on an exchange. But If you have a bit of idea you can use non-custodial wallets for you to have full control of your bitcoins and do some precautions like safe browsing and not downloading random files over the internet, also not be baited by some "coinbase impersonators" that offer free bitcoin or whatever. There are many alternative wallets like a hard wallet that I personally used to store most of my bitcoins.
If you got that ideas and you understand the risk the chance of being hacked is small.
But if you don't have it and you are willing to learn more about it, securing your funds should be more secure using hardware wallet.
Better to invest spre money in buying those hardware wallets than keeping your assets inside centralized exchange. Learn more about it
and keep yourself protected.
