Utility is dead!
Look at what coins now are doing, it's all hype, fomo, vaporware, and nothing else!
All the utility is about creating meme and swapping meme coins, they've realized that actual utility is way to hard to obtain and even major coins fail at this!
So no, advertising 1 billion people might use it will work only if people are gullible enough to believe it, but in the current state of the ecosystem, there is no future for actual utility.
