Winning:
Depends on the credit card. If you know what you're doing, you can call them and request a higher approval, and then they might ask for tax returns or a W9 or 1099's. All are good.
Winning, while I might be a "funding ninja", I didn't invest the time into creating this method, I found that having more options was the best method of making money. I just refer it out, so I try to work on passive income on these and focus on things that can make me larger sums of money, like real estate or MCAs. I actually refer out and profit-share most of my credit card processing clients as well, it's hard to sell more than one thing at a time.
