First of all, people who understand Crypto market and have knowledge about it, won't expect to cross their altcoins more than 100x something. 100x altcoins are shitcoins or could be memecoin. And that could be luck game or gambling, which is another topic. But mainly we should focus good altcoins rather than shitcoin and supply won't matter you are choosing good altcoins. You should remember that, the project is only matter. Supply doesn't impect that much except in token price
Yeah that true only meme coins can go up to 100x and there are only one or two examples of them. Mostly the projects claim that much pump but in reality even the marketing team knows that this is not possible.
Jokes apart but these kind of projects only target the greedy people and amount them the newbies mostly. We need to feed it in our mind that no coin can make you billionaire over night. Crypto is also like a profession that needs good strategy and time to gain profits.
