If you don't already have some shares, then yes. How about this process:
* You want to borrow 1 BTC from me, and I am asking GLBSE shares as warranty.
* In evaluating them, I will use the current bid price for your chosen shares and I will let you know how many I need.
* You send me the shares via the GLBSE interface, I send you 1 BTC.
* When the load expires, we reverse the transactions. If you don't pay back, I keep the shares.
I suggest you buy LIF.B shares, they seem to be a very legit business:
http://lifunds.com/index.htm . I also own a few optimalbitcoin shares, but the price doesn't divide right for such a small amount as 1 BTC. So, using LIF.B as an example, you should buy 8 LIF.B shares, current ask price is 0.12 so it will cost you 0.96 BTC. For me, these 8 shares would be worth their bid price, for a total of 0.784, but I am willing to take that risk, since it's an experiment and you are established on the forum.
Risks are as follows:
* for me:
- if I send you 1 BTC before getting the shares, you can disappear.
- you don't pay back, I keep the shares, but I might not be able to sell them for 1 BTC and I either have to wait to get dividends off them, or sell them at a loss.
* for you:
- if you send me your shares before you get 1 BTC from me, I can disappear with your shares.
- even if you pay me back 1 BTC, I can keep your shares without returning them.
Since I am not an old member and have zero public feedback, I think your risk is larger than mine, so I am willing to be the first to send you the BTC and shares.
Of course, a loan company could create a very nice scoring system based on there price/market movements/past results, and include other means of influencing the score. But that's a story for another time.
So, what do you think?
