People have been predicting an altcoin boom for months now and so far it have only been the low market cap coins that exploded from time to time. If you also take into consideration that Binance is no longer going to accept users from the US, even less fomo capital will be pumped in the coins they have listed.
Even the XRP army has finally taken a few steps back. They're way less aggressive on social media right now than they were at the beginning of the year.
the big altcoins aren't capable of pumping EXACTLY BECAUSE people have been predicting their boom! you see the only reason why people come on social media to hype some shitcoin and talk about how it is going to get pumped is because they are bag holding it (and usually are in a big loss) and want to see it pumped so they can dump and get their money out. and that is exactly what they do whenever there is a small pump, they dump to recover something like 10% of the 80% loss they sustained.
meanwhile small altcoins don't have that problem since there are not that many smallcoin bag holders as there are bag holders of coins like ETH, XRP,.... so they can easily get pumped without much resistance.
