With that said, I also dislike these kinds of speculations because we have enough "when moon?" people in the space. I'll make this slide though, just because it's Hal Finney.
It's definitely a good idea to seperate the shit crowd from those who did everything they could to deliver something that makes the world become a better place, which is what Hal Finney heavily contributed to. I can respect such early on predictions from these legends, because they focus on the fundamentals, while all the idiots who entered the market in the last years want to see moon to sell.
The whole crypto market is basically an IQ test. The smartest minds support Bitcoin and to a certain degree Ethereum, while the rest is busy counting how much profit they would make if coin X or Y goes up like 500-1000%.
