Currently, the biggest challenge with altcoins is: the rapid shift of hot trends, making it impossible to conduct in-depth research before they become outdated or the whales abandon the project and run away.

In the past, altcoin hot spots usually lasted longer, allowing for a slow understanding of the whales' intentions and giving traders time to rest.
But now, although altcoins are more volatile, their duration generally lasts only about a week, with extreme surges and crashes in a short period.
Ordinary traders simply can't keep up; by the time you see a price, it might have already changed to another.
In the past, it was possible not to make money; now, traders are worn out physically, and making money has become even harder.
Playing with altcoins now is almost like gambling…
