Well if you like censorship resistant, fungible, private money that the state doesn't want you to use there is Monero. I find its use case pretty compelling
Networks effects are important, among other things. Unfortunately monero is too small to be considered viable and any other coins chances of competing against #bitcoin in the PoW arena are unrealistic. https://youtu.be/SANFAxu9mqg 
I agree network effects are important.
I disagree ASIC resistance is silly. Monero's hash rate is solid and not at the mercy of specialized manufacturers. It's easier for an individual to mine Monero and it'll be that way forever.
The point remains that Monero offers a compelling use case for those who need or want private money. Even the guy who coined "there is no second best" literally said "if you need privacy maybe you need a Monero" lol
Straight from the horse's mouth
