There is enough that one can find in way of huge problems with Ethereum, it's fundamental program, which I've seen many highly technical people say that it will never be fixed i.e. it's a mess from the get go to its very core. With billions already had, the ball is running and nobody seemingly wants to hear or know about this. You can go to the ethereum forum and also find a whole page of various attacks on ethereum, all the while as the internet and crypto community seemingly brushes this problem under the carpet for the sake of mega dollars. With IOTA's tangle I've also seen a very good youtube video on this with an explanation that because there are no miners involved, the way it operates, you can hack the back of the tangle chain and create a fake parallel line and fool those that come after into thinking all is okay. By the time this is detected, the hacker is long gone. As most crypto veterans know, there's a lot of BS, fake, copied, pie in the sky, crypto's out there. There are some really great crypto's also, sadly there are some really great coins that get pushed to the side, when they shouldn't be and other coins get notoriety for the wrong reasons and agendas. In a perfect world, I'd want to get the block chain people together and really work this out i.e. UBIQ, Ethereum, Block etc. I'd also want answers from IOTA regarding this backdoor hack exploit, of which you'd never hear about from most sources. It will take years before a lot of the scams are detected, well after humongous amounts of money have changed hands. PS Thumbs up for Steem.
