Not as crazy as it sounds really
Let's put it in perspective
A. ETH has been .10 BTC before
Can it happen again? sure
B. In the next BTC bull run, can BTC go 5x it's ATH? sure
C. Can both these happen at the same time over the next two years?
....because IF they do....
....1 ETH will be $10,000 if those two things happen
