BITCOIN MINING IS A HUGE SCAM (MATHEMATICAL PROOF)

After doing some consulting in Bitcoin mining with several clients and monitoring the payouts and the declining profitability of their operations in the last 3 months I found this scientific paper that proves that Bitcoin mining isn't profitable, regardless the variables that affects it.

Please check this graph that speaks by it's self

The network difficulty is increasing exponentially and profits are decreasing inversely.

Thanks to Bitmain and their everlasting offer of new batches of mining hardware, that affects the payouts, it proves that it is a major scam.

Best case scenario, miners will only get their return in one year. :(
