To the investors in ethereum I can comment that they are not alarmed, it is possible that the price already this to raise.
I remember a few months ago, in fact in January if I do not remember, the Ethereum was at 8 $ and I told a friend, What do you say, we invest in that currency?
His answer was clear, we did not not invest in that as it looks at its low cost, it will not go up.
We were wrong, now the currency is at 322 $ and we lost the opportunity to compare at least about 5 Ethereum but the world of cryptocurrency is like that and the best thing you can do is to invest in some of them because they will always go up, sometimes they will fall but , most of the time it is to grab momentum and double its price.
