copy and pasted quote! "Yes, I will still control the funds I use to purchase MasterCoins. That's why I can go all in"
Can you re-word this sounds like you mean you'll make up a number and class that as an investment which I'm sure you don't mean!!
I know you've spent a couple of years on it, but it all seems so rushed. It's a bit worrying that your whole system seems to rely on third party escrows, which it looks like you've tried to find without success for your fund raising.
I'm also a bit worried about a couple of the points you said above
-"the gold coin probably being backed by funds in escrow" sorry probably not exact quote, but if this is the case then you're not backing gold. Surely to create a gold coin you need to have a predetermined value in weight held in escrow backed by a coin.
-Also in your paper you comment on strengthening the escrow fund automatically through good trades (by low sell high), when the user above commented people could trade against this occurrence you brushed it off as doing your job and making money... It seems like it was just over looked and would surely undermine the strengthening effect of the escrow fund as described in the paper.
Although you're using a different method, it seems there's a lot of similarities in your paper with the open transaction project; (please collect me if I'm wrong on this still reading through there stuff now at a couple of the sources below)

BTW wow you're funds have just shot up from 35 to 1,257 BTC while writing this so you must be doing something right!!
