Hi Luc! I have a security question.

I keep reading that it is unsafe to keep money on the exchanges, but of course I need the money on the exchange when the drop happens.

Is it actually unsafe even with two factor authentication turned on everywhere?

If so, what is the best way (lowest fees) to quickly get money from a wallet to an exchange?

And should I pull out all of the money after every trade? Every night before I go to bed? What are the best practices for this sort of thing?

Thank you!
