TON (The Open Network) is the most popular altcoin in 2024. This telegram based coin is becoming very popular nowadays. Especially since hundreds of projects are currently collaborating with this coin. Moreover, there are some other coins which are very popular in the market especially NOT, DOGS these two coins have become very popular nowadays.
I wouldn't consider them (NOT, DOGS, and other P2E giants) for long-investment though, but TON itself - sure, it will live on, that's my opinion.
