Newbies have been warned several times not to leave coins on exchanges, my question today is about exchange security and I'm going to use binance as an example

1st Question: binance exchange and few top exchanges I've used has finger print scanner under security settings, I want to know if this can only safe me from people around me or also online hackers, both withdrawal and deposit requires my thumb print, how good is this ?

2nd Question: my second question is almost same thing as the first, which is 2FA, it's part of my security settings that login, deposit and withdrawal requires 2FA codes too, how tight is this from hackers? And of course people around me ? Thank you


Note: I'm not planning to leave my coins on exchanges, not that stupid but I'm a full time trader and I use binance so I just want to know

what I am experiencing right now is that it is difficult for me to obtain profits from investments and trade that I do, & is there someone here who has more effective ways for me to be able to improve my trade and investment so that I can get a profit of course, not vice versa I get is continuous loss.

No where in the world is currently safe from Cov-19 and there is lockdown in every country today, this is the best time to gain people's trust, online job seeking have increased through Google search and new people are getting into crypto investment, what is the best time to release your project if it's not now?
