Credit cards have low APR's right now. I'm curious to know how many of you are using this credit to buy things, expand your business, build onto your house, otherwise buy things that you may not be able to afford otherwise. Alternatively, you could use this money to bolster your trading account. After all, your trading is your business, and businesses borrow money all the time, and there is always the risk that you may not be able to pay the money back. What I am interested in is those of you who are usually profitable and are using low APR's to borrow some money. How much are you willing to borrow, and where is this money going??
