Bitcoin will always recover and in fact it's already recovering.
That the price went as low as $3000 doesn't mean that BTC is dying out. That's the volatility of these digital currencies.

I dont think bitcoin cash can die. It's better and faster than bitcoin. Just like eth is folk of etc. we need more time for people see what bitcoin cash can do
