In 24hours I will release a new mod with 0.1BTC buy in and 2% fee. The algo is very profitable with my modded kernel.
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.
0.1 BTC, $268 might be a bit steep for some people, especially if it's a new coin. We wont know how profitable it will be until it hits the exchange.
Sigt definitely paid off though. Even if I cost 0.1 BTC, I personally will still be purchasing it.
