Maybe it is not possible since I don't think it is a traditional ERC-20 token, because of the dual token system with WAVES/ETH?
There is no surprise that Cryptopis delist ETT as there is no trade volume at all.
I don't know if there is a future for the coin. But no doubt the dev team is just bustard, from the very beginning to eat their word to gather more fund than they promised to do.
