Ethereum:

The biggest problem with Ethereum is ICO's. ICO's are becoming a thing of the past and STO's are starting to takeover. This could save Ethereum from plummeting further, but the issues is with the fact STO's won't be as big of a craze as ICO's were. STO's require REAL results, while ICO's were just ideas and white papers. STO's require REAL investors with a BIG net worth, while (most) ICO's allowed anyone to invest. The main issue is that not many people will be able to buy into these STO's. There also won't be as many of them as ICO's. I think STO's could actually be successful and potentially great for this community, but their impact on the ETH price won't be near as great as ICO's were.
