TON and Sol are the most popular crypto at the moment and are driving a great volume. Meme coins for some years have been the single largest group of coins that leads the market. Meme on Solana had been particularly more popular last year and now this half of the year, it looks to be dominated by TON. Notcoin was probably the most successful coin on TON chain and following its footsteps, there are hundred of other meme coins and copy cat launching on TON. How successful they are going to get is a different thought process but they do have the hype at the moment.
Memes will move to TRON with time, in my opinion
The volume on SunDog and Tron Beer is quite scary already, and SOL with TON should think about the possibility of this big trendy group of degens going out of them to other chains
