Are you sure it is getting a lot of adoption on exchanges?
I'm not even sure that's a big positive, even if what OP said is true, which I'm not sure of as monero has been listed on tons of exchanges for years now anyway.
The thing about bitcoin is that its one of the few cryptocurrencies that can actually be used as money to buy stuff from merchants, which I believe was one of the intended purposes from the get-go. But monero? I don't know any place you can spend it, and I'd like to see some evidence that it's being used on the dark web. It makes sense that it would be, but I've never visited any onion sites and so I don't know if it's really being used there.
Aside from that, I've got no problems whatsoever with XMR. And by the way, most altcoins have much lower fees and much faster confirmation times than bitcoin. I wish that weren't so, but that's the reality.
