OUCH!! That is one hell of a drop. Indeed, it is all about timing, which is why I use XLM. Not only does it have 0 withdrawal fees the speed of transactions is very fast so (provided you're not super unlucky and there is a massive sell off) then you should be able to action the process before losing too much. It is also possible that it goes the other way...but that never happens that I am so lucky!
Happy New Year. Thanks for the feedback :)
