Rather than all this complications if you need money urgently and don't want to touch into your Bitcoin why don't you just get a loan normally without ever bringing your Bitcoin into play.
Getting a loan from a bank is not easy. You need to provide collateral or a mortgage and depending on the country and its crypto regulations, many banks might not even accept Bitcoin as collateral.
Lets say this is the situation that I have put all my money into Bitcoin, I dont have any other assets left and I need some money. How can someone give me a loan without any collateral, since I dont have any other assets? I think if the money is needed urgently or for something very important, selling the Bitcoin would be wiser. I mean at the end of the day, why are we investing so much? To live happily right? If selling the coins and getting the work done is possible then you should probably go with that OP.
