Most gambling sites that offer 10x bonuses have extreme wagering conditions that will rip of all the bonuses, sometimes you end up losing your deposit but when you are lucky, you may win a few times but can never win an amount that will make you reach the minimum withdrawal
Also, there might have many other restriction to receive the bonus because there might have unclear rules, many games won't be count as the wagering to collect the bonus. And many sites ask kyc if reach the wagered and bonus. And finally they scam the deposit bonus by the name of bonus.
Reaching the minimum withdrawal will not be easy as that will need us to play longer and spend more money unless we are lucky, as you said. Maybe before we deposit some money, we need to check the KYC section on the terms and conditions on that site to know if that site requires KYC for their members or we do not have to do KYC. If finally, they scam their members, that will be necessary to avoid that site forever and moves to the other site.
