This doesn't look like a strategy to me at all. It is more like a future story to me
.
My best strategy during the time of crisis would be something like
1) Find out why the prices are dropping.
2) Analyse the charts and predict if the price will drop further.
3) Sell your coins and buy back at a lower price to gain an increase in capital.
4) Enjoy more profit when the price increases
For anybody who finds it tough to do the above should just hold on to what they have. Never panic. Chill out and stay away until the crash is over.
