Recent bad news has come to the cryptocurrency market. Many major social media sites like Facebook, Google prohibits the advertising of cryptocurrency, because there are too many fraudulent ICO appear on their site. This makes Ethereum prices fall deeply, currently prices are fluctuating around $ 400. However, I believe this is just a cycle of Ethereum, it will quickly recover and rebound in the next few months. So we should buy and hold from now on if we want to make a profit later.
