I have read dozens of threads saying you need to keep your BTC on a hardware wallet or paper. Anything online isn't safe they say. When trading that is not really feasible is it? I like to move in and out of positions several times a day and often at a moments notice. My trading account has a sizable balance (to me - 5 figures) in it.
How risky is this and any additional things I could do?
I suggest you make 2FA security on each account that has a lot of BTC, minimize the crimes that occur in the online world, if it installed 2FA I think it is safe.
yes, now this is the most secure way to protect data. But if a hacker decides to crack your wallet, then you do not save your coins. So do not talk about your income. Money loves silence
