LoL... Bitcoin is just... Bitcoin. There will only ever be 21m of them, it's trustless, and decentralized. Fixing issues is something for people to do, not a crypto-currency. Although it could certainly help.
The reason a fiat currency can potentially crash against BTC is the sheer amount of new fiat currency being printed has reached ridiculous levels (along with net negative interest rates) and bitcoin just highlights that incredibly well by being deflationary. Essentially just by doing nothing Bitcoin gains in value just because fiat currencies lose so much value on their own daily.
Example: a rib steak that used to cost 0.10 cents 90 years ago now cost maybe 100x that now. The rib steak itself didn't change, it's the currency purchasing it which has drastically decreased in value against it.
