Bonuses is pretty common on crypto casino. Crypto casino like Metawin which you can find on my signature space always have different bonuses every day that you can take advantage. Metawin is just newly launch sportsbook so we can expect for the big promotion in the near future.
I advise you all to shop around for other sportsbooks/casinos that offer you bonuses because they make huge differences to your profits and betting strategies.
I agree on this in general but you always read the ToS since some casino lock rhe funds until bonus is active which you can’t be forfeited unless you loss all your funds or complete the wagering requirements.
