Anyone considering to take this offer: be careful, there is something fishy about it.
Generally, those how use referral codes take advantage of their popularity in social media like Twitch, YouTube or Twitter/X, in order to pocket some money with each registration and deposit from people who joined the platform from the referral link or code, nobody who is seeking to profit from those referral programs is going to offer you money to use their code.
Besides, there is no warranty OP is going to actually pay you what it is due to you once you have registered and wager the bonus you are going to alledgedly receive.

Don't be gullible, people.
Of something seems to be too good to be true or too easy too be true then generally it is not true.
