What's the downside to selling a CC and buying to close it out the next day to collect 100% of the premium?

Stop responding back to this thread. Also I came on here to ask a innocent question to see where and if there were gaps in my understanding. The fact that people on here are so pretentious that they want to slander me and patronize me for “not knowing options” and making me feel stupid is exactly what is wrong in this world. You ain’t mister king ding a ling. At one point you were new to this as well so get off your high horse and start helping others instead of making them feel stupid. Case closed.
