Edit: this is not some stupid game or scam. There is a very serious reason for this research. And you will eventually come to know the reason. Please do help me ascertain the market rates for the above loan.

Yes it is. a NLockTime transaction is not valid until the time/block set by the transaction. Until that time/block, it would be trivial to double spend the transaction. The only way to protect against this is to fund a transaction to a 2-of-2 multisig address and then sign a NLockTime transaction from that multisig address to the lender's address.

Thank you for correcting my error. I didn't study nLockTime carefully enough. I see you are correct.

Let's change the specification of the OP to your suggestion to sign the BTC to a 2-of-2 multisig, then the borrower signs the multi-sig with the nLockTime. So then the lender is in control and can submit the multi-sig transaction after the nLockTime has expired. Which is the intent of the OP.

There is also the risk that there will be some kind of fork (hard or soft) that would invalidate the NLockTime transaction that would prevent it from ever confirming.

nLockTime times can apparently be specified as Unix timestamps, so how do you envision a fork invalidating nLockTime transactions?

Do you mean that some crazy Chinese mining cartel takes control of Bitcoin and decides to remove that feature for no forseeable valid reason?

The higher the interest rate, the happier I am. So I am hoping you can explain some valid risk.

What about the risk of BTC/USD exchange price changing during longer terms, is that a risk/opportunity cost that concerns lenders or are we BTC permabulls here?

Also realize the OP did not propose any monthly payment schedule as we would normally see with loans:

Lastly, what you are claiming to propose is that the lender sent you BTC and you subsequently return the BTC to the lender immediately with interest (at least from your point of view).

Agreed you're correct. I know it seems illogical, but there is a very valid case where this is extremely profitable for the borrower due to an externality. I will end up telling you what this case is much later, but I can't tell you now. And the reason for the borrower wanting this is irrelevant. I want you to operate on the assumption that once the borrower explains the reason, you will clearly agree without any doubt it is not a scam.

Btw, this is a very high economy-of-scale scenario. We can handle say up to 1000 BTC, maybe 10,000 BTC. But I will accept feedback in increments as low as say 50 BTC.

Please try to give me some feedback on what an appropriate market interest rate is for various terms. I need this feedback to do some important calculations.

Thank you sincerely.

Edit: also this is not an illegal activity that is being funded, although one might be able to claim there is some risk of regulatory action. So please factor risk of very small chance of regulatory capture (seizure or holds) into your offers of a market rate because no such regulatory action has yet occurred while numerous instances of these loans have been presumably done (and I can't get data because they've been in private).
