My personal opinion (and everyone is entitled to one - I do believe in freedom of speech) is that your sp mod is too expensive for the small miners. Big miners can easily afford it.
Exactly , way too expensive for majority of miners are small mirers and dont have hundreds of 1080 Ti to make it worth it such extraordinary price for a piece of optimized software . Most people living in apartment simply dont have that much power available , 12-18 graphics cards is near the limit of circuit . 0.05 btc is $650 dollars , its crazy expensive especially considering modest boost it gives . When bitcoin was low $ wise , SP was selling for same 0.05 btc , it was like $250 on average and was affordable and actually worth it ROI wise for small miners , now bitcoin increased many times and he still charges same 0.05 btc . Wheres logic ? If you sold it for $250 or around that figure a lot of people would but it , you would actually make a lot more $$$ . But no , lets try and charge small miners absurd prices and wonder why no one is buying
Please reconsider the pricing and make it reasonable for most people , and make the price in FIAT to BTC , adjustable depending on Bitcoin value . Maybe in 1 month bitcoin to be 20000 ? What you still going to try and charge 0.05 btc ? Or maybe it will be 30000 , 40000 , 50000 , still 0.05 btc ?
