I dont really believe that the ethereum will cost even 600 dollars, it was a very good and long time. At that time, it was necessary to sell ethereum. And I will buy ethereum for $ 50.
believe it or not, but sometimes things like that happen with time. because the kit never knows the conditions that will occur in the future. then we must continue to believe first, if the back doesn't happen so we know.
The price of any coins, eth including is very unpredictable with time. And we never know what would happen any time in the future. But eth, just like btc, is one of the good coins to invest on. Considering its past trend, it is surely a good coin for long term investment. It may be in challenge right now but it will surely recover in the future.
