I have never invested in either of them till date and am never interested in investing in them. I have definitely heard from people that profits can be very high in meme coins and NFT, because their prices suddenly go up, giving you high profits in a very short period of time, but the risk of loss is equally high as their prices may drop suddenly. There are definitely some nft's that have a future and they definitely have a use case somewhere.

So instead of investing in meme coins if investment is done in nft then it can be beneficial, but here again you need complete knowledge and experience of the future of the NFT you are buying.
I personally prefer investing in top coins in the market rather than investing in NFT and meme coins.
