Thank you, @acesontop!
Btw, in 2017 I followed very closely the situation on the crypto market. And at that time I worked as a cryptocurrency analyst for a very big brokerage company. So, at that time I wrote many articles and analysis about price of Bitcoin and crypto (probably 2-5 a day). The price rise was due to a hype/FOMO. So, the price of Bitcoin formed a BUBBLE. I have seen such kind of situations many many times, and I experienced it personally back in 2008. The Bubble unfolds almost always in a similar way... And I was able to predict back in 2017 in December that the bubble will burst ... exactly when Bitcoin hit $20 000 and retraced to $14 000 (last days of December).  Then I wrote for many leading media outlets in Russia that it seems that's the end of the hype...Anyway.
