I've sold all my ETH when they reached 0.015 BTC. I feel bad about it now that they're over 0.017, but frankly I feel safe. I don't like it when I'm in front of something I don't understand. There's just no reason why ETH is gaining so much value so fast. Can anyone explain what's going on? The market is irrational. Hey, the quicker the rise, the quicker the fall.
