what is the use of buying from store mining ? what is electricity used for? what is rack ? what is stuff? what is the minimum threshold and payout to where?
1. Miners from store will bring you more power. More power - more BTC
2. Electricity is used for mining, but it will be enabled in the near future - now the use of electricity is FREE (yet)
3. Rack is a place where you can put your miner to mine BTC
4. Stuff will also be enabled in the near future
5. We have no minimum: you can withdraw as much as you have earned
Hope we have answered your questions! Have a nice mining!
