I'm really curious about how you can afford to sell that with no electricity/maintenance fees.
Let's change it to 1TH as I don't know who still speaks in GH, this ain't 2013 anymore.

So, 1TH for 1 year, 19$, that means 0.052 per TH per day.

Bitdeer is selling $0.0629 TH/D + Electricity Fee $0.0432 T/D, that's double.
ViaBTC is selling $0.0518/T/day + Electricity Fee at 0.05184$ again double, plus 6$ maintenance fee.

So, how do you manage to do this twice as cheap as some really old and proven competitors?
