Not soon, even dash can't, dash is no.1 anon coin, monero is no.2, maybe ethereum has the chance to replace bitcoin, but maybe in 10 years.
Dash is not even close to being #2. Coinmarketcap.com is valuing the supernode capital on an MTM basis. If that capital, and the stealth instamined millions were to float on the market, dash could drop 90% in a day.
All of the monero is floating. The cap numbers for Monero are actual, legit numbers.
But yes, not soon. I think somewhere in the 2020-2024 range it is likely that 1 XMR = 1 BTC. But both will be at a much higher fiat/gold price by then.
