They're almost dead right now, and even if Pavel Durov will try to make them alive. I don't think that people are too naive to follow his words. Because he's trying to build that ecosystem, not the tap but with his ton ecosystem. It's no sense to hold worthless tokens unless you make fun of it or you're so happy about it. Those airdrop tokens that have some worth in the past will no longer have any worth in the future. Only a pump and dump can make them have some worth. But, that usually only happens when we're in the bull run or near to it, that's probably one sign. However, most of them are dead as good.
Ah, yes. Durov's little crypto venture. I've thought TON was going to remain in the spotlight for long, since it was tied to a popular messaging app (Telegram). I guess I was wrong. This was an overhyped "shitcoin", just like Solana and gang. You can agree to disagree, however. That's the problem with altcoins. You never know which one will go to the moon or which one will go down the drain in an instant. It's like gambling. In "meme" coins, the situation is worse. That's why many investors prefer Bitcoin on top of everything else. Not even ETH is worth it.
If you're still inclined to invest in altcoins, only choose those with a proven track record of development and innovation. Usability is a must these days. Without these qualities, you'd be wasting your time and money. Only invest what you can afford to lose. We'll see if altcoins make a comeback. Time will tell...
