Ethereum support for new coins to run smart contracts on its block-chain. I think it is the main benefit of Ethereum . mainly there are so many ERC-20 coins. these coins are based on Ethereum network. still so many ICOs are offering ERC-20 tokens.
That is by far the greatest characteristic of ethereum, it makes the creation of new coins way easier, but unfortunately this has not been the blessing that we were looking for, because most coins that are created above the ethereum platform are not really that good and the devs are only taking the shortest path to create their coins and be able to scam investors as fast as possible.
And then in conclusion about the fact that there was a lot of projects are abusing the platform right now. So many scammers are using it right now to create a short-term coin that will be used by them to get fast bucks and then they will run away with that money. ABLE project has become an example of that.
There are so many examples of scam coins being developed above the ethereum network that we could save time instead by trying to find the projects that are any good, however while I do not like that scammers are using ethereum in that way it was almost inevitable that it will happen, since developers looking to create a great project will probably not do it above the project of someone else.
