I like Monero very much and it is totally plausible that it overtakes BTC, but I doubt it. To do so, it'd need mass adoption well-beyond what we see today. Although us freedom-lovers understand why privacy is critically important, the uninformed masses have been led to believe that its primary appeal is crime. Therefore, I don't see it as a competition as much as I see it as just another option for specific uses. BTC can be a non-private store of wealth like Gold and it will just sit there idle. When I need to actually transact and have all the real fears you've cited, perhaps I'll consider Monero then. I was reminded of a quote today on Twitter that I really liked: "When privacy is criminalized, only criminals have privacy". source: https://en.wikiquote.org/wiki/Phil_Zimmermann - creator of PGP - the encryption protocol that we can thank for much of the crypto we enjoy today, directly or indirectly. Think on that!
