I think we are still not safe in Bitcoin that hackers might hack our wallets and might have get an access into it because they are now hightech this era. They can get an access anytime they want but of course their target are whales or big players of Bitcoin. But don't be afraid because I know some platforms that has security features like, Binance, Poloniex, Bittrex, etc. that they recommend to us to download Authenticator to have additional features that gives another password to log-in and cash-out. I know it is additional task to do but if it's for our protection.
