If this is the CASE THEN ANYONE CAN CREATE TOKEN WITH THERE NAME AND START SELLING THAT TOKEN,
I knew what you mean. There are a lot of token created with same ticker name, but not all of those smartcontract was verified.
they are asking people ETH without creating token, and when the token is not created then what they will burn
If the token not created yet, there are not any tokens will burn. They just create the token as their token sold and their calculation.
For example : Vooglue use this method. Oh and also Tokenomy also did this method.
In this case, the smartcontract has verified and have the total supply. So I think they will burn if the hardcap not reached. And then distribute the tokens as per investors bought
