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 do believe that you already got a lot of good replies but at the same time I do believe that you have to actually consider taking care of the personal security too, which usually includes the mobile and cyber security. If your mobile is bugged you won't be able to do anything about it. Yes the coinbase is a good platform and I do believe that you can move to other amazing wallets too , but for the while you have to be aware of the fact that :
You have to refrain from weird sites or download any content from the internet
Use only trusted sources
Make sure and don't tell anyone about your wallet or keys
Etc..
Personal security is as important as choosing any wallet therefore be careful about it too.
