In the future I don't know... Most likely Monero will die, chances for this is still pretty high.
However if it will not die, it will go to sky highs and replaces bitcoin (marketcapwise).
No offence but both of these scenarios are ludicrous. As extreme scenarios, neither of them are likely, and neither are there any logical reasons as to why it should be a binary 'either/or' situation.
It is unlikely that the dark sector can eclipse the transparent sector in regards to global adoption, and right now there is no logical reason as to why Monero would drop the ball as the de facto leader in the dark sector.
