There is no ideal platform, everywhere there are dissatisfied users. I think that this project will also have some difficulties. Although the prospects for this idea are really good.
I think its very interesting project!!!
But interestingly your blockchain will be developed?
Our blockchain development is in progress
I think that an own blockchain is essential to this kind of project. I hope they don't have too many problems with it once it's launched.
I think there maybe minor issues that will arise once the mainnet had been launched but I'm confident in the team's ability to resolve it asap.
