Well... I've seen logic go out of the window in previous crypto bull markets. The market has always surprised (if not shocked) to the upside. $166 in 2020 seems truly insane, as the XRP market cap will be something like 7 times that of Amazon. If that happens, then BTC would also have to pump to around $350k to hold on to its number 1 spot.
But who knows, you might be right. I think that people will have to re-evaluate the meaning of "market cap" once BTC overtakes Amazon anyway (this would be achieved around the $55k range)
