Just to vouch for SP. I purchased the sigt mod at the very beginning. With 21 - 1080 Ti, I made $7000 mining 152,000 sigt.
His miner was 30% faster at 70% TDP, so his mod contributed $2100 in earnings.
your farm is definitely bigger than mine His miner was 30% faster at 70% TDP, so his mod contributed $2100 in earnings.
I purchased the mod 1 day later and so far I barely recovered price of the mod (I didn't sell coins, just calculated current price). if sp_ will charge 0.1 BTC for new coins' mod, it will deter small miners like me.
