I'm just curious why do you want to apply blockchain and decentralize stuffs to your business project while you should easily be successful without it?
I think they are just using "blockchain" as a means to generate more funding for this project, mainly Ethereum network.
Just don't make sense to me.
It could be for more funding but at this time, crypto investment is pretty low, like investors are no longer interested to invest in a new project and with that said, their 2 decades would be useless. They eventually will fail and probably will exit scam.
