I've tried both free bet and deposit bonus promo codes, and deposit bonuses generally offer better overall value. The code from promo code for 1xbet provides a deposit bonus which means you get extra funds to bet with beyond just free bets. Free bets are nice because there's no risk to your own money, but the amounts are usually smaller. Deposit bonuses give you more total betting power and let you build your bankroll faster if you meet the requirements successfully.
