All this money pouring in ETH comes from those ICO's recently that have succeed and also the upcoming ICO's we have right now which are commonly erc20 tokens. They raised a huge amount of funds in terms of ETH and I think that is what's causing the ETH pump right now. Also, there might be manipulation by Chinese but sooner or later ETH will go back to it's real value.
Ya I mean holy shit. $400 an eth? For what? Byteball does smart contracts. So does counterparty. So does ... so many alts. Why do people think these tokens are going to do well? If eth fails then these tokens will just be useless right? Or am I totally not understanding how they work? They rely on eth right?
In crypto-coins the most important parameter to consider is not features (Bitcoin would be dead if this was the case) its the trust people place in it. Bitcoin was been around since a long time, so people are reassured about it, Ethereum on the other hand has been created not a very long time ago, but a lot of big organisations trust it which is also important for the public opinion.
