To reach level 1, attaining 10,000 XP (~$6 in wagering BUX) is required.
If you don't feel comfortable adding it to the list, it's totally fine.
If the site requires a fresh account to reach 10,000 points by wagering around $6, I can no longer consider it free coins or a free crypto faucet. Because of that, I wont add the site to my table. Had it not been for that requirement, it would have found its way to the OP.
Even Wolf.bet has an untraditional rewards-like system where you have to come back every day (for 7 days) to unlock all rewards. However, it's still free, and all they ask of the player is to enable 2FA.
