Mining with A3 miners is going very well, we are currently doing it, and is our most profitable miners currently!
Difficulty is not pushing up as hard as everyone expected because as the A3's are coming online the GPU miners are pulling out so there is just replacement of hashing power and the network is more efficiently mined, less power to produce more coins. Really good for the network, just like what happened with mining dash.
Expecting difficulty to go up next month with the new batches being released but difficulty going up makes coins rarer and price will follow with a delay if it follows all the rules.
Interested to understand the Siafund and how it is linked to Siacoin, what are you buying with Siafund?
Are you buying shares in the actual business?
