This is not the first time it happened but for so many meme coins exist or continuously launched by devs we don't know on which of them will pump the same with other meme coins since for sure investor doesn't know on which are the tokens could possibly bring them a lot of profit the same of what OP highlighted on the topic.
Absolutely, it is a pure gamble but with little bit of insight and analysis there is less chance to predict the outcome of it for the short term and that is what some bump and dump investors try to succeed and its not really for everyone and this shouldn't be a primary focus for the retail investors.
