Looks like this coin is getting MURDERED by huge mining farms.
#1 miner on nanopool is sending 500GH/s. That's like over 500 GPUs.
Looks like the difficulty will double by next adjustment in a few days.
Read my post on top of the page...
The reason for double difficulty and hashrate skyrocketing is the release of a dual miner for ETH/SIA.
That means that the massive power from the ethminers using this miner now is partly directed towards SIA.
Many of the miners probably stay with ETH/DCR.
But SIAs diff will double or more with next adjustment.
I think this is a weakness of the coin... diff should be readjusted more often.
If the ETH miners moves away from SIA after diff update, the original miners will be stuck with blocks really hard to solve and for a long time.
