z-cash mining is the best you can do now if you are into mining ...the initial price was around 25BTC and gradually it reached the current price of 40$..
From 25 btc to $40 . What are you serious that it yielded you 25 btc at one point of time?
That is massive and unbelievable if that its actual then it wont take time to even reach $10 in coming month.
It was around 22 BTC when it started and lasted for about an hour, so maybe that guy might have made something out of it.
After an hour, it got dumped straight away to 2 BTC and rest is all you said.
It's getting damn hard to trust any ejected alts so easily, still, people invest and cry.
