This guy is correct.
Lol hes completely full of crap with that three prong nonsense. 300 is his number because months ago he made a post when Ethereum first went to 450 that he was sad he missed the boat and would buy in at 300 if it went that low again. He has been saying 300 is his arbitrary buy low point for months. Ill track it down if he denies it, but its a lot of pages back and Id rather not.
The $300 is my arbitrary number based on when I am comfortable buying. It also happens to be just under the all time highs for Ethereum BEFORE the massive spike.
