Bitcoin's price has crashed due to several reasons and not just because of the covid-19 alone.
The plus token scam and dump might be one of the major reasons for this dump.
I agree with you, but even if the scammers did not dump their token, we will still see this dump because of the covid-19 has already become a pandemic, people panic, it's a normal that we will see a dump but maybe that this huge.
This is the reason of the big dump, whales manipulating to cause more panic.
It could be the whales manipulating the market and ride with the current pandemic.
Nevertheless, covid-19 just caused too much panic for the people to choose the needs to survive rather than diversifying a budget for investment.
