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?
https://www.bitsler.com/en/dashboard (Daily wagering contest that can be done with play money)
https://t.me/StakeCasino (Daily challenges that require no deposit but small tasks to complete)www.freebitco.in (Hourly faucet claims, you can easily get 4-5k satoshis per day using their reward system, eventually and gamble everyday or wait a few days to gather more satoshis)This is a good idea for new peoples who have just started into the crypto community and now wish to make some profits and to start their career into the decentralised world. But what you are saying is only possible if any of such website is offering higher amount of bonuses. There always is higher minimum withdrawal so it does not always be possible to withdraw small bonuses.
Like stake casino has minimum withdrawal of 0.002 BTC which is really much hard to collect from bonuses or faucets. faucets offers much lower amounts on each claim which would even be in a two digit satoshi which won't have any importance.
