The best thing as a crash happens is to buy and hold your coins, Buy more!!!!. I remember when I bought Bitcoin at $800 and it dropped to $300. I bought more. Waited and forgot. Now it is about $2500. Think about that.
If you want to be a day Trader then think about that every day!
I'd rather think of a couple of good long term ICO's. Then set and forget.
Just my strategy !:)
Thanks
