What are your views on the first crash? When will it happen? What would be the price of bitcoin after the crash? What is your strategy to survive it?
"surviving a bitcoin crash"?!
Come'on, it would be silly to put all your wealth into bitcoins, just as it would be silly to put all your wealth into any single financial asset.
There are other places where to put your money. Precious metals, stocks, real estates and so on.
I doubt anybody would get seriously hurt by a bitcoin bubble crash. Only some greedy fools will.
