Don't assume that all traders have the same abilities, most traders who we don't know are still likely to make big profits with their trading approach. Even on newly listed meme coins or altcoins, they can still make profits although this method cannot be recommended for beginners.
Yes, those are still traders even if they only trade during the hype that's being made from meme coins or altcoins that are just recently listed. That's actually a strategy that anyone can rely on. Being on the hype while it's still fresh, you can make money from it short term. It only takes capital and bravery to take that risk because not everyone that follows that strategy are earning. There's still a lot of risk that comes from there if someone will do the same what others have made them profitable.
