Altcoins are accepted natively. This means you can just send your altcoin to the altcoin address given by EarnBet on your account to deposit funds. Once you send the altcoins to the altcoin address, EarnBet will convert the altcoin automatically to a WAX token at a 1:1 ratio and a 1:1 value. This specific altcoin WAX token will be added to your WAX / EarnBet account. From here you can bet at EarnBet.io just like normal. Once you're done playing you can withdraw these altcoin WAX tokens directly to your own altcoin wallet/address. Technically, this means you transfer the altcoin WAX token to the EarnBet contract. From there, the real altcoin will be send to your given altcoin wallet/address also at a 1:1 ratio and a 1:1 value. For both deposit and withdraw the transaction fees (if any) are paid by the player.
