Without advertising, no one would invest in DOT, and their low rating in terms of market capacity means that the coin's future will end if it does not do something good in the coming months.
It is difficult to trust a project that has not risen when others have risen.
If a coin can't survive without contact publicity and even with that huge amount spent it is going down against competitors that's a clear sign something is terribly flawed or simply put there is no demand for such a product. Coin aren't special from other products, when you spend more money on marketing than others and you get fewer results than one who doesn't spend a dime
you need to change your product. But in this case, well, they are trapped until a new hype like web3 or defi or the previous ones!
Its a good project, decent investors but still lacking why ? because there's no latest major upgrades.
Bitcoin hasn't had a major upgrade since Segwit, taproot is a minor thing, doge is basically the 2017 version and there isn't anyone spending money other than fans their own funds.
Yeah, I understand upgrades, but how many users actually want and use those upgrades?
