Most of these 'decentralized' gambling sites linked in the OP also don't seem to offer anything new from what more centralized casinos offer
Actually, some decentralized casinos offer "on-chain betting." In other words, the calculation running on top of smart contracts. This way, after they (casinos) deploy smart contracts, everything is automatic, secure, and transparent.*
*Please correct me if I'm wrong since I don't have the ability to review the smart contracts.
Instead of looking to those kinds of DAPPS, if you are investing you better trust those reputable casino's that are offering bankroll investments. You're more secure with that kind of investment scheme that these established casino's are offering. You have the trusted casino with trusted people operating the business.
Those casino's that has been running for years and has a good track record.
But like what I'm saying, it's not about the system but it's about the reputation and where you are going to put your money.
There is no such thing as
trust and
reputation in relation to online casinos that don't have licenses, not a legal limited liability company, etc.
When $ 1 million bankrolls are safe, there is no guarantee if $ 1 billion bankrolls will be safe. This is the nature of human, i.e., greedy. Since this is the bitcoin community, you should have known that centralization is bad.
