This is nothing new since all of premined coins and recent issued coins are not the best. Still older altcoins are doing fine and maybe soon we finally get some fresh ideas for coins.
This topic is a bit weird. Is this things still going on or is it old news. Why no ones is posting here ? I would expect at pointy when everyone went idle that problem were solved but apparently something is weird here.
It is not death of all altcoins. Simply recently there were a lot of new coin that were clones of older coins or already premined. Idea of having many altcoins is there is free market and best coins can survive. Right now there are at least 10 altcoins that are doing fine. In future when people again get creative and creates new idea for altcoins market will move again.
You still can just sell small part of it. Also you can get more and more services and products for bitcoin, so maybe instead of selling it for $ you can just use it as normal money. Buy yourself house, nice holidays and pizza
