Well in this case your writing has given off the wrong impression for me, at least in the underlined part. There you kind of imply that there is a chance for this project with massive marketing, but this is not true for something that is such an obvious scam. Sure if they throw a ton of money on it they may be able to scam a large number of people with it, but that won't make this project legitimate. It was just a misunderstanding then.
The obvious scam you talk about—is it as a result of the majority of the tokens being held by the team, or is there another sign of a scam that we are not seeing? A team holding a major number of the total supply is dangerous, as they can dump it anytime,
When the supply is this concentrated you don't need to look at any other factors, it is a confirmed scam. Stay away from such projects. With millions of tokens on the market, you can always find something that is more real and less risky.
but since the token has been there for over a year now with no existing scam, it's less suspicious if you ask me, although they might still be planning for a big pull-off.
The age of a token does not provide legitimacy, it is part of the trick. Sometimes scammers will even try to buy out very old projects slowly and then revive them in an attempt to scam. Just stay away, stop overthinking it.
