How many Altcoin Genesis-mining is supporting? Please anyone can give me a number?
BitCoin (auto)
DarkCoin (auto)
LiteCoin
DogeCoin
AuroraCoin
FeatherCoin
LotteryCoin
MegaCoin
ReddCoin
BlackCoin
There, all current coins. And you do NOT need to choose Megacoin (but you should). Auto means the most profitable coin is mined and exchanged for either Bitcoin or Darkcoin.
I think selecting Auto is the best option. It increase the chance of getting profit from mining.
