Just because some completely useless thing gets pumped after being advertised, it doesn't change the fact that what you are talking about is participating in a market manipulation scheme.

When you view it that way, things start to change. A market manipulation scheme aka pump and dump, will obviously increase the price of that garbage (token, coin, stock, etc.) but it is fake.
Can you make profit from it? Sure.
Can you lose money in it? Sure.

So stop thinking you missed out just because some shitcoin got advertised and pumped. Think more realistically about the risks. If you are willing to take those risks and if you know how to get in and more importantly to GET OUT, then start trading these shitcoins that get pumped and dumped.
