The era of shitcoins is fading away and there are alot of heavy funded tokens/coins being developed it is expected that these old tech will disappear in the future.
If that is the case, then you are predicting a market collapse because of the hundreds of coins on the market, how many actually server a purpose or used daily by people other than traders?
The era of shitcoins only began in the last few months.
Doge to me has more "street cred" as a coin than 85% of the actual coins on the market, even though it also serves no purpose, it has a few things going for it, nostalgia, resilience and uniqueness with a small clique of followers around the World.
Not saying it is a good investment at all, but there have been and will be plenty more shitcoins to come and die a slow death while Doge will always be there.
That in itself gives it some intrinsic value.
