Donations were chosen to judge "public interest"; part of the social analysis that I conduct to find out how to best integrate the concepts for public dissemination. It is a general rule that those who are interested in something will contribute towards it - we left no stated amount so that individuals could choose of their own free will and of thier own accord to what amount to contribute.

I have thought a lot about your idea. I am going to consider your entire system a "black box". I know nothing about how it works internally but I do know that I put BTC in and I get BTC out, right?
You may not know this but the price of BTC is very volatile.
In this example I deposit 100 BTC in your "bank" and tie it to the USD internally by choice. Now internally you either hold the BTC or you sell them for USD on the market right away. You must do one or the other. Assume you hold the BTC and at the time I deposit the coins the price is $200 per BTC. So I have $20,000 on deposit, right? I come back a few months later and ask for my $20,000 back. But assume the price has dropped to only $100 per BTC! In order to get me my $20,000 you will need to give me 200 BTC but you only have 100! You will need to go buy 100 more BTC in order to pay me back my $20,000 you own me. This will cost you $10,000 right out of your profits!
So I conclude that in order for your system to work you will need to sell the BTC as soon as you get them - or you might go out of business very quick.
Therefore you will need to hold accounts with every kind of fiat money that you allow people to choose.
Yes, there is an internal liquidation cycling mechanism. A reserve of BTC is held in liquidable form (ie on exchanges), a reserve is held in hard assets, and a reserve is held by which we run through a full liquidation process to avert risk exposures during the process.
Like a grain of rice on the scale, the system must be maintained in a balanced format. But after it has amassed enough weight to maintain a neutral equilibrium it is always self righting, and self correcting, using real world price marking to calibrate the foundations and structures for the operations, en masse.
And yes, you put BTC in, to make a 'purchase' so we can make a recordation to our internal units of conversion and exchange, and when you draw off the ledger it is like 'liquidating your interest' in that particular ledger value; payable IN BITCoins, the equivalency of which is equal to that of the The Then Market Currency Value. What you do with the Bitcoins when you receive them back in your wallet is entirely up to you and under your full control and pervue.
Thanks for your question!
