It seems the ethereum price has decreased far from the beginning of the year price.
But ethereum still good to invest because many peoples using eth to invest their funds to many ICO's
looking forward is the best thing to do , if todays price is almost half of the past price then it is better to buy and invest in ETH because there is a lot of possibility that eth will repeat that price and if that happens you will earn from your wise decision.
My friend it is really good to invest ethereum because of thw transaction for tokens that we can't directly to bitcoin but to pass through to ethereum and specially for gas transaction.
