But what would you check for, if you were to trade a token on premarket today ?
Honestly I dont do premarket cause the basis is quite vague. I am aware on the token you are interested with though. I have sign airdrop and will claim later before listing. You are right, the project owner holds a very useful product tokentable that itself make it a strong contender. What if sign holder can be drop some tokens using tokentable? Who knows the opportunity for sign is good and very possible.
I do pre market if the project has utilities and the hype around it is genuine and not generic..

For sign it seems it listed 60% above the pre market price, which is good imo..
