Altcoins popping up like in a game "whack a mole". Some did 50%, some did 5x. Is there any methods that could be used to predict which altcoin will be next? (I guess there must be some indicators, narrative and etc.) or it is purely random game?
It's like lottery, you get a ticket and very rarely there is a chance of winning. Obviously you do not buy lottery ticket thinking you will be a billionaire, the odds are very low and you are aware of that. However, that doesn't mean you don't get it neither, because if you spend just a few bucks and get a ticket, that means you have one chance, and having one chance is better than having zero chance.
Even if it means 0.000001% chance, it still is better than zero. This is the same in tokens, many invest amounts they are willing to lose, because they believe it's better than zero. Doesn't mean they think these alts will make money, it just means they throw money at everything, small amounts, and maybe a few would hit. That's how they predict.
