Your comment reminded me of this post from a few years ago.
It will be interesting to see what projects are still around a few years from now, but the Internet went through similar phase also, right? Most of the companies burning through money before the .com bubble burst were worthless also.
I own some Monero. Same reason I have some junk silver and a little bit of gold. Good for a rainy day in case you need it. If the government went crazy and cracked down on all cryptocurrencies, I'd be happy to have some private coins I could use.
