Are you going to create your own blockchain in the future?
Why do you think they need it?
Ethereum blockchain is not stable sometimes, it can create a lot of problems. Remember the case with CryptoKitties
Ok, I see. Maybe it is worth doing in the future, but they have o such plans, according to their roadmap
Unfortunatelly, the roadmaps reflect real plans very rarely. They will change everything several times, I think
