What I've learned is that no one knows anything. Besides a very small portion of people who have studied stocks, economics, and trading their entire life, we're all just making it up as we go along. If you believe in the technology, buy it now and it will eventually go up. If you try to time the market or spend all of your time looking at charts, you're going to drive yourself insane. I check the price once a week, and browse this sub and /r/ethereum for any interesting and exciting news. I know it's become a meme, but hodling is the safest way to eventually make profits
