Today I lost everything. I was making profits until noon, and then it skyrocketed from 3108 to 3170. It was all gone. Not only did I lose the 300U profit made today, but I also lost over 300U from yesterday. In the evening, I clearly made back the money, but Ethereum went crazy, with fluctuations of 30 to 40 points in a minute, no pattern at all. Now, the 20U challenge I started has nearly 100U left.
