So first I did studied a lot about ETH minding, even I invested tons of money for mining it.
Later on I did some calculation and then decided not to mine but hold. ETH minding will be impossible by September or so investment on GPU and other stuff will be useless, and after all observation I can bet ETH will cross 1000$ by September, Why?
Detail: ETH minding depend on block system, thats how miners get paid. but later in September ETH block will broke and Electricity will cost mining more than they will generate ETH, so ETH have to be increase to complete the need of miners and as there will be very less numbers of miners left, ETH will increase to get companies involved so it will bump to 1000$.
Will it compete with BTC? Answer : NO
BTC is not going up due to mining, BTC became a live Giant so that's something else.
Good luck guys :)
