Which coins can I mine? What about GPU mining?
We only mine Bitcoin.
We use ASICs SHA256 mining machines, no GPUs.
Our machines can be extended to merge mining for 3 other coins:
Elastos (ELA) https://www.elastos.org (1 BTC = 1 ELA)
Namecoin (NMC) https://www.namecoin.org (1 BTC = 1 NMC)
Hathor Network (HTR) https://hathor.network (1 BTC = 120 HTR)
The payouts are tiny, so you may decide it's not worth the time of setting up 3 more wallets.
Still, it's a no-cost extra that could amount to something in the future and does not affect your BTC mining hash rate.
Thresholds for payouts are:
0.5 HTR
0.1 NMC
0.1 ELA
