Bitcoin can be a good buy currently, but I don’t think ethereum is a good buy and will increase like other crypto currencies. The reason I don’t trust ETH anymore is that the government of many countries have either banned ICO’s or have made regulations on them. Moreover, the social medias are taking action against crypto currencies by banning advertisements of ICO’s and new tokens and projects. Therefore, for a smart contract platform like ETH the number of ICO’s launching has reduced and so we haven’t seen much growth in price of ETH.
