I'm not buying ETH at these prices, but I have started mining it a little bit with a nice GPU that I just got.
What you're describing OP is typical in a lot of markets, however. Nobody wants to buy X when X is near its all time low, and then all of a sudden when its at its all time high, everyone wants in and it's like panic at the disco with people elbowing each other trying to get buy orders in and filled. And so it is with ETH at the moment.
It's a fantastic coin, don't misunderstand me, but the time to be loading up on it was precisely when it was going for $150 and nobody wanted to touch it. Investors are retarded and never learn when it comes to that. You have to buy the air conditioner in the winter when they're on sale, not in the summer when everyone is trying to stay cool.
Good idea, not bad but still it depends on how much you buy that gpu and how much this bull market will be around for, if bear attacks the market today your rewards through mining will decrease alot, if you are making 5$ per day it might go down to 2$ per day, it's not a bad time to build a rig but GPUs are way too costly right now
