Keep in mind 80% or more of the tokens of the average poopcoin are held by whales and insiders. So whenever you see an altcoin pumping by a large amount it is almost always caused by whales and insiders injecting large amounts of liquidity to pump up the price to get retail excited to buy in just before dumping on them. The suckers fall for it every time. This kind of insider manipulation is common in the stock market but is much worse in the poopcoin casino.
Another thing about altcoins is that they are not seen as a long-term store of value (like bitcoin is) but as a means to make a quick buck.
The average shitcoiner has the attention span of a bipolar 9 year old child and will cycle in and out of different altcoins like changing their dirty underwear.
Whenever a shiny new altcoin attracts their attention, they will dump whatever they are in and go to the next shiny new shitcoin.
So you cannot rely on altcoins as a long-term store of value. Which is why some predictions of ethereum going to $10,000 are not realistic,
because that would require large numbers of people holding onto ethereum for many years, which they generally do not do. The unlimited supply of tokens doesn't help either..
99% of shitcoiners are day traders and casino gamblers not long-term investors.
