ETH prices continue to fall below 400. Is this really necessary for ETH to really explode in 2018. Or is this just a bubble?
Ethereum is not a bubble. I think you should be patient for the current market situation, all crypto coins fall low. Do not be too quick to conclude the situation, this is only a temporary decrease, later you will also see that ethereum is not a bubble.
Well it was when it was at its all time high just like bitcoin was, now it is back down again and it is probably going to start pumping as soon as the bitcoin does the same thing.
