I'm thinking of getting a loan to buy more bitcoin, as I'm guessing we'll reach $10K in a few months it can be a good deal to lend at a bank against 5% anual rate
Did anyone do this before? Would like some experience advice
You're total crazy. It's a very bad idea to get a loan to increase your bitcoin balance. Bitcoin is too much speculative for invest a great quantity of money (Especially if you get loan for invest). Try to earn in other way.
