I am bitcoin maxi and I like monero. I don't store any wealth in it, but I use it for dark markets when I need it.

The main difference between shitcoins and Monero is that Monero really solves the problem that bitcoin does not. And it is true PoW coin with no premine. Will monero overtake bitcoin? Unlikely. Does it have it's place? For sure.

If my friend wants to buy something from dark market, I'd rather have him use monero than explain how to use bitcoin privately via coinjoin.

Privacy is important. Privacy by default is what we need for cash. Gold had silver as it's satellite. Bitcoin might have Monero.
