DELIVERY DATE: APRIL 2019.
Who knows if Ethereum will even be mineable at that point in time.
I try to think positively:
I hope ETH is still POW forever (it's just a joke)
I hope the ETH price will return to the planet Mars (everyone's hope)
I am worried if ETH switches POS before APRIL 2019 (ignore this)
GPUs never dies (hope of all GPU miners)
And this's the point for those who want to start mining (2018: year of disaster)
There is simply too much uncertainty with that kind of investment that i'd say it's even worse than gambling.
