Logically it is very difficult, because we need another 19 times price increase, in other words we need a 19 times increase in Bitcoin marketcap.
(If) today the bitcoin marketcap is $2T then we just multiply it by 19 and the result = 38, we have to be at $38T bitcoin marketcap to get bitcoin price at $1,900,000. with the same amount of supply. Huftttt is fun but I can't accept this hallucination.

Back in 2017 the bitcoin marketcap was still below $300 B, and with high fluctuations it is not surprising that it can get a very high multiple.
