It must be meme tokens.

You can try to see it by yourself to see the chart owned by the meme tokens. It was growing so crazily. Look at how slerf or even degen have been doing massive growth in a short time. I think that fi you are talking which altcoins have performed best this year and it must be meme token.

You must be specific with your question. If you are also asking about which top tokens that have been doing massive growth and it must be solana. It grows from less than 10 bucks to the 150 bucks in a month.
