The fastest deposit methods are e-wallets, cryptocurrency and electronic credit/debit cards. E-wallet transactions are processed instantly; cryptocurrency deposits take no more than 15 minutes for BTC and are faster for ETH, LTC, XRP and BCH; the speed of credit/debit card transfers depends on the bank (sometimes payment processors delay or block transactions, for example, if the money transfer falls into the potentially fraudulent category or violates payment provider rules). The slowest method of funding an account is a bank transfer of up to several working days.
