I checked out the project and they appear to be the real deal, hence the delay.
Combo (aka Cocos) is far from the real deal. They may have appear like that because they splurged enough money to get listed on Binance but essentially they are just another shitcoin that is playing a long game and slowly dumping their tokens onto community.
They screwed over old bounty hunters by changing smart contract of the token (after hey sent them tokens, making them worthless) and hired God knows how many shill accounts to write thousands of shitposts in their various ANN threads. Another thing, I can't imagine any quality altcoin project giving $100k worth of their own tokens to a bunch of low level spammers as that's what these bounty hunters are.
I suppose they are looking for the optimum time to distribute these tokens
They will probably distribute them once they are done with it and tokens are worthless. Doing it now is too risky as that volume on Binance is propbably fake and coulnd't stand bounty hunters selling their tokens without wrecking the price.
