I invested earlier this year and had profits. The advise is that it's best to go out when you are at the top. Meaning that if you buy cryptos and their prices have risen giving you good profits enough to satisfy you, you sell. Not wait and hold and be greedy. Never be greedy. If you want less risky path might I suggest Merculet ICO. The company has solid team and innovative technology backing it. See my Signature for more details.
