Honestly, I just heard about Meme Sniping. If you just take new memes that have just been registered without analyzing them, I think it's suicide. As you said memes often lack utility and an established roadmap, and this means we are just gambling when entering the market and this is not very good. And usually after a coin is released there will be a price reduction because many investors sell their coins to secure profits from their investment. Many experts recommend to not holding memes for a long time because many memes are worthless after being released.

I think this trend is just speculation and it will not work for a long time because there is no clear analysis and no basis at all.
