After the current fall in prices, which has already dragged on for a bit, I think that many meme coins will no longer be able to rise to their previous price level. When the holders of such coins see that they not only do not grow in value, but also fell sharply and continue to lie, this is very sobering.
As for fraud, it was, is, and, unfortunately, will probably always be in the world of cryptocurrency. Confidentiality, relative anonymity, communication via the Internet, which makes it possible to be anywhere in the world, the concentration of significant funds in cryptocurrency, the presence of numerous newcomers with no experience in this market, all this creates a good environment for fraudsters.
Unfortunately, same things happened during 2018 as well. Things like BCH were seen as second coming of bitcoin, there were a ton of miners using it and it was just seen as the faster and better way bitcoin could have become, I never really cared for it at all but at least I do understand it, now look where it is, the coin that was third coin at one time, and now it is not even in top 20 anymore, and probably going to be a lot lower as well.
I do not think that Doge is any different, I believe that doge will be outside of top 20 in a few years, and if you made your profit already then it is great, but if you haven't and still holding then I am sorry but you should get out and get out quickly. I am not even getting into whole shiba or whatever other memecoins, they are not going to be even in top 50 if you ask me, it will take a long time but they will be down for sure.
