Is it still worth it or is the difficultly too high?
The market's looking good that's why it's still worth it.
Is mining low value coins still going on or are most resources now directed at the established GPU mined coins, albeit at much higher difficulty?
Any new coins on the horizon that may be worth a punt?
I'll rather choose to mine those established coins than those low valued coins and believe that they might grow someday. Go to the
Mining (Altcoins) and get to follow many threads there for you to have more idea in getting back.
