Interesting, so it was a serious question; I might be willing to make a loan, if he were to put up 4 BTC as collateral.
Not trying to tell you your business, but you do understand that's it not so much a loan, more you selling him
BTC at today's price and then buying it back at whatever rate prevails at the end of the month, and getting $10 for that risk?
I wouldn't be buying it back though; he's essentially asking for $1000 USD, and he'll pay me back at the end. Maybe I'm too tired and I'm misunderstanding the question though.
Ok, read this when you've had a sleep
Let's say you do the deal as originally specified.
He wants $1000, paid in Bitcoin. At $375, that's 2.6666
BTC you send him. In exchange, you get an IOU for $1010 and the escrow holds the collateral until the end of the loan term, then releases it back to him on receipt of the agreed $1010.
You take the $1010, but wait, the rate has gone up to $400 in the meantime.
The $1010 now only buys you 2.525
BTC to replace the 2.6666 that you originally gave him, so you lose 0.1416
BTC on the deal. (Of course, if Bitcoin/USD goes down, you make a commensurate profit.)
Without a loan clause authorizing the escrow to deduct any change in the exchange rate, it's not a loan, it's a private bet between the two of you on the future price of Bitcoin.
Yes, you don't have to see it that way. See it like you use your dollars from your bank account. You buy btc with them (you can also pay me in other ways, but most of them are more expensive), lend them out and sell them again when you get them back. Then you have an intrest rate of 12% instead of the 1 (I even think I don't get that here) % on your bank account.
I'm really honest and really willing to pay back. I understand that in the long term if bitcoin crashes the collateral would not be enough (and technically I could run away) but I'm willing to adjust the amount I have in collateral. Make it lower when bitcoin price goes up, make it higher when bitcoin price drops and keeping the collateral at 120% all the time. (monthly, weekly, or even daily if you prefer but probably escrows will not agree with this). You don't have to do this but 12.68% a year without any risk instead of a 1% on your bank (maybe even with a bigger risk), don't say this is a bad investment, maybe you don't do it because you are bullish on bitcoin but for some people this could be interesting (for people who don't care about the bitcoin price and just want a good safe investment with their dollars), but till now I didn't find anyone yet.
I am lending US dollars, no bitcoins, you don't have to forget that. If you don't have dollars and don't want to sell anything for dollars this is indeed not a good investment.
