Imagine how much money lost people if more than 80% of their investments was unsuccessful

Cryptocurrency market falled 2 years. Even Bitcoin in the beginning of 2018 was 20 000$ now it is 10 000$, other cryptocurrencies and tokens lost much more in value.
And then after 20,000 dollars, bitcoin cost 3200-3500 dollars, now imagine how much other people who bought at that price earned! So this is all relative, someone is losing, someone is earning.
