I see that in April Traxia will move from ETH blockchain to ADA blockchain in Q4 2018. Why this transition and how will this shift change the project? Why do not you convert right now before the ICO is sold out?
because Cardano does not have the smart contract feature yet, it's something they'll release later on.
I think that this might have been totally normal and as this project in not that matured then ,it will take time.
