Recently I have been thinking about this ''strategy'' that is free but difficult to pull off. Essentially you would go from casino to casino, getting all the bonuses and welcome bonuses they give and trying to rollover them to eventually withdraw the money won. This ''strategy'' is obviously risk free since you are not using your money, the clear downside is the rollover part, 100% of the bonuses they give will need to be wagered 20 times, 40 times, 100 times, whatever it is, it's always a huge number so you clearly need a lot of luck but hey, you are gambling, you need luck anyhow, right? I think we could make a list of the best casinos that offer the best bonuses here, any ideas?
I did it long time ago when I was so active in collecting free bitcoin through some giveaways, no deposit bonus, or free spins. You are right that it is risk free as you do not need to spend anything to start, but nowadays many sites requires some deposit first before you can withdraw the winning from the bonus once you complete the wagering requirement. There is also max amount that you can withdraw from it, there was no max amount that can be cashed out in the past. Even worst, nowadays most site will ask you for KYC to withdraw your winning from free bonuses.
In my own experience sites when crypto are still building up especially when it is not yet experience the hard pump the free site such as faucets or spins are very legit even though you only get few but atleast it is paying you can withdraw it while now there is so many sites now and it is true that it is paying at there site but when you withdraw it there is a lot of reasons that in the end you can't get wht you work for.
