No. While some websites do generate a promo code for you to use to redeem your welcome bonus, many don’t. In fact, most online crypto casinos process welcome bonuses automatically once your account is registered.
For casinos that don’t do this automatically or use a promo code, you will find your welcome bonus under your player account. From here, you can activate the bonus by following the on-screen instructions.
Other sites might ask you to manually enable the offer, usually on the Deposit Page.
