Hi,

I need some expert to gauge whether a BTC Mining investment I am offered is profitable.

The cliffs:
- 10k GBP buys 1k MHs for 3 years.
- 50% of profits will be retained by the company
- the most profitable of the currently 14 most liquid coins is mined and exchanged into BTC on a daily basis

example calculation with the assumption = BTC stays constant at 250GBP/BTC:
30k GBP = 3k MHs mine 13.05 BTC in 3 weeks = 1087.54 GBP
after 50% fee = 543.77 per week profit
after 3 years = 84828.12 GBP

Is this realistic?

I would be happy to pay a consultation with an expert via Skype if this is not completely unrealistic.

Amen to that, I'll come back to mining one day, in a house with walls made from solar panels 

AHA! The real reason behind global warming! Damn Chinese!
