That's what I liked about using a CC was that the funds were available instantly and I could send whatever I bought to another exchange and buy what I really wanted to trade for immediately, not a week later. In this case it was an experiment to see if my card company was going to charge a fee for crypto purchases. I had no idea they'd disable them altogether! I have plenty of credit cards (most of which I don't use because the rewards are lower) so that's not an issue, it was just very surprising.
