I’m not sure this belongs here but I’ll ask it anyways. If I have a 20k purchase to make over the next few months, does it make sense to open a new credit card with 0% APR while buying a 1 year treasury with that 20k I would have used to pay it off? I will be earning upwards of 5% on that cash. Yes, I know my credit score may drop significantly, but it would only be temporary or I can open a business card instead.
