I would like to ask a question to customer: How can it be profitable ?

I was looking for a 15th/s which cost $6400 and $0.0015/gh/s a day.
So basically we have 6400$+ 12x657$ for one year : $14500 a year.

So if i use coinwars calculator http://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=15000&p=0&pc=0&pf=0.00&d=47427554950.64830000&r=25.00000000&er=288.01000000&hc=6400
With constant diff and constant current price of btc/usd it would generate 16720$ a year which mean only 2220$ of profit a year.

So it would take 3 years to just return on the setup fee (6400$).

But this calculator is wrong because difficulty is raising with time, and generated btc is lowering with time for constant hashrate.

if i use https://bitcoinwisdom.com/bitcoin/calculator with a 20% raise of difficulty, it's never profitable.

So what am i missing here ? and what can make it profitable ?

 

Awwww, why GM on recovery? The quality of our service has never changed. The amount of payout depends a lot on external factors such as Bitcoin value, difficulty, luck, etcetera. Obviously we do not have control over those. But we do have control over the mining part, and we do a very good job at that, which is the service we offer. You know we can do it because we have been doing it. Always.
