First time I've ever seen projected statements of cash flow in a cryptocurrency whitepaper. Crypto is growing up 

I won't invest directly as 20% of that investment is directly lining dev's pocket, but hey, at least he's being up front about that.

I will point hashrate at this if it's still possible to mine it, though (no sound on my current computer so no point in watching the mining response video).

I also think you should immediately do the legwork required in contacting the devs of Sterlingcoin and Britcoin to be listed on the Banx exchange. Don't rely on the community here to put you in touch with them... show the cryptocurrency community you're a part of it, rather than seeking to extract 20% of your targeted 10,800 BTC investment from it exploitatively.

Though the multi-pronged business strategy could work through diversification, you'll have to do really, really well at each. This is not the case so far. What I'm seeing at Banx.io (3 currency pairs and a terribly thin trading interface) leaves me unimpressed.

What are your plans considering BTC's value is so much less than the USD500 as per your entire financial projections?

So far this seems primarily like a venture to put 2160 BTC in Mark Lyford's personal wallet.
