Honestly? The best tip to survive this market crash is simply to lose your 2fa device (lock it in a safe so you can't access it) so you can't touch your orders that are set for selling at a profit.
Next, stop looking at charts, start looking at news so you can find signs of a bull run.
And that's it. This will prevent you from selling at a loss.
This will just ease your mind for a while, locking it will not help since you will just think of it still especially if you start plenty of fuds and since you know how to access it you can easily get it anytime. Having other stuff to focus too and eliminate being paranoid will be better like studying more about crypto and how these chains can effectively be used in more projects or having some insights to other ICO or just relax for a while and breathe.
