If you are aware that an asset is traded purely out of hype and there is nothing behind it then it is better for you to stay away from it, since it would be way more difficult to make money with an asset in which you do not believe at all, now NFTs are for the most part a bad investment as a great deal of the volume we see in those coins is not real and it comes from people which are laundering their money by purchasing NFTs of their own creation.
But, I think not all hypes have a bad side and what if there are positive news about btc that it looks like they are now hyping it, will you still comment the same? But I bet you will like it more that way if only btc and the top coins are the ones that they will going to hype all the time and not those newly created scam coins. Those who launder money are I think not related to the person behind the nft's. It's just there are so many criminals in this world and they are looking for ways how to get away with their bad deeds.

True because if you don't believe the coin that you invest, you will not hodl it for a long time but why would you invest on it anyway? What matter is your beliefs and not the others or the hypes that you see.
