The ethereum is constantly decreasing in value and many think that is si not only because of the stock market crash but because ethereum is no longer a trustable cryptocurrency which is the reason why ethereum in five years may be depreciating in value
In my opinion, Ethereum is still a trustable crypto currency it just the team involve in the project are not much stronger/working simultaneously like before which I believed some of the team back bone have moved to EOS/NEO just like some miners moved to BCH when the forked happened but in the meantime Ethereum will get back on track once the team fix the problem. However, can you say Ethereum is no longer a trustable coin when the ICO project still use it?
