btc..ltc..vtc..drk/dash..and eth now..
vtc is always a gpu coin as the coin devs determined to keep it that way.
I'm planning to purchase GPU of $200-$300 and then buy more time-to-time. But it'd be pretty bad to see once ether mining becomes useless. GPU miners will have to explore some sort of replacement.
Dash is x11 and there are x11 ASICs which means it's a bad choice for GPU mining.
I used Minergate (does not pay out) and according to how fast I can make dash by the hour and what the electricity would cost, it is actually profitable for me to mine with a GTX 460
Is minergate completely making up fake numbers on how much Dash I am making?
For the X11, it has ASIC. It will not be profitable to mine with the latest GPU, let alone a three generation old card.
