I understand that 1 WTT token is supported by exactly 1 Watt of capacity. I hear people have problem renting tokens out - so there is free capacity.
However when I asked their Customer Service about that, I was told to come back in January...
Due to delays and long deployment process it happed that currently there were more tokens issued than mining capacities working, that is why there are people with tokens who can't rent out 100%. I am about 15% of tokens not rented out, and rest is rented out.
But this situation should change in December when most rigs will be deployed, and those who rent out now, will start using these tokens for themselves to mine.
That is why GW says to you to come in January. They are not sure how thig will go, because there may always appear new requirements from US officials which may delay deployment again.
