I think all these coins has something that makes then a lot different from each other. There are people who still believe that dogecoin is good. It seems to be coming back after a long time of sliding back. One thing I have noticed about dogecoin is that it is quite different and is not the type of coin that just pumps and dumps like that, instead it takes time to grow and when others are pumping like crazy, it doesn't follow that same route, it stays cool and when the market has gone to being stable that's when it starts its own growth. You should do more research and get to know about it before you go ahead to invest.
