Yes, real money is the preferred method for funding your legal Kansas sports betting. Online sportsbooks take a variety of deposit types, including credit cards, debit cards, Visa gift cards, Bitcoin, checks, money orders, bank transfers, and various peer-to-peer solutions. Please note, however, that only Bovada accepts American Express and that none of the big sportsbooks will take PayPal from US-based customers.
When choosing a deposit (or withdrawal) method, it’s also important to be aware that online transfers (like those used for Bitcoin, peer-to-peer payments, and occasional card chargebacks) are always faster than their old-school paper counterparts. If you’re using the former, expect a few hours’ turnaround. If you choose the latter, give yourself a week or two of lead time.
