How does the customer make profit?
A: Bonus payouts are calculated using the formula: unpaid principal (BTC) * 0.45 (satoshis per BTC per second) * time to find a block (seconds). Mining revenue will first be used to make bonus payments, the remaining of mining revenue will be payment towards the purchase price.
So basically contract will expire on 120 days and little bit more if initial payment hasn't been recovered, in this way actually hashnet will own your mining device after contract finished and what you will get as bonus payment will be really low return for you and more mining hardware added to hashnet mining rig.
How this can be considered as profitable, somebody in-light me on this. I think like all cloud mining contracts this one is also not profitable.
