To take advantage of the bonus offer, users must use the promo code CRYPTO100 when making a deposit in the cashier. However, it’s important to note that only players based in the USA and Canada are eligible for the bonus. Additionally, the bonus can only be used in the sportsbook section of the BetOnline platform and cannot be used for other sections like the Racebook, Casino, Poker, or Live Betting. Despite these restrictions, the CRYPTO100 bonus code provides a great opportunity for sports betting enthusiasts to receive a bonus boost to their account balance, allowing them to place more bets and potentially increase their winnings.
