Same with you, I started to involve in bitcoin when the price is $400 and now I can't believe the huge price. That time I earn my bitcoin through ICO's and I trade it with no doubt. And now I don't have any of bitcoin and it's my big mistake.

I'm sure the reason is the pandemic, people want to earn money and bitcoin can do that. Not only the simple people also the some companies, and the pumping of price is because they invest their money in bitcoin for possibility of profit.
