You are aware that bitcoin.com is selling 1 year contracts @ 35 bucks for 1 TH/s, right?
So they've got half your price, are an established company, and have basically no downsides, that I can see.
Why should anyone choose your service?
Yeah, but with daily fee 1.40 USD your profit is a negative value. (as is shown at price chooser)
We do not have any additional fees, so everything you mine for 24 month is yours (miner fee and electricity price are deducted while withdrawal)
