I don’t think there is anything wrong with altcoins. If bitcoin is pumping, most altcoins don’t pump instantly, most of them do pump gradually, but it doesn’t happen immediately when bitcoin starts pumping, so all I will tell you is to have patience. If bitcoin doesn’t dump, with time they will also start pumping gradually, but if bitcoin price dumps, then those altcoins are also going to dump more. Whenever bitcoin is dumping, altcoins are always dumping also, but if bitcoin is pumping, altcoins don’t pump instantly. I have heard about those altcoins that you mentioned, but I haven’t invested in them or done more research about them, so you just have to be careful when investing in altcoins.
