2018 is a very unsatisfactory year for cryptocurrencies. People overestimated the development of this market. In fact, the market broke out in 2017 because of the crazy ico, but this year people no longer believe in ico, so there is no more money to enter this market.
I don't think so. Though we've been on a hatd decline since the end of 2017, money will still come pouring with crypto garnering more awareness as it goes on. Icos may not have that much influx since investors would be thinking twice or thrice with a lot of research become making ny cashouts but that would only make the market's image better.
