You can’t Cash App money directly to any legit online casino, but you can use CashApp to make private P2P payments to fellow site members who are selling vouchers. Cash App can also be used with the third-party MatchPay service, which effectively makes the voucher process faster and easier. These services are currently limited to a small selection of top online gambling sites, however, so if your site doesn’t support vouchers or MatchPay yet, you can use Cash App Bitcoin transfers to load up your account.
