Widespread use of cryptocurrency is inevitable. Whether or not it's mainly Bitcoin is irrelevant.
BUT, what comes after all of this? We are so focused on crypto's use being an inevitability and speculating on future value to make money when such profit potential will not last.
Once cryptocurrency is universally
used, it won't make sense to keep it as an investment as the price will stabilize.
After the widespread use of crypto is realized, the ultimate representation of how everything has become digitized (even value), the rest of our lives will also have mostly become digitized.
Being hooked to computer screens and smartphones will turn into being hooked on perfect simulations in virtual reality where everything is cheap and our minds can theoretically live on indefinitely for next to nothing. Value won't even have to be exchanged for the most part as consumerism will be obsolete.

This is sort of like saying, "When is the flea on the dog, going take ownership?"
BTC is $68B USD cap, US-DEBT is $600 Trillion in USD ( take cdo, and all debt forms, not just Fed-Res book, or US Treasury )
So BTC is so small compared to the dog, that he's actually smaller by proportion than the flea,
What matter's is when all this corporate 'back debt' takes on crypto for its books.

Regarding your question, Security & Privacy are missing form BTC, but the PTB don't want that, that's why the NSA/CIA pushes BTC hard, but its also why CHINA has diversified,
I suspect that given CHINA owns all crypto-space, that in TIME they will release the one true coin that rules them all, but china also will not give the sheep a coin that provides privacy, or security.
Thus its up to the little people to make their own 'super bitcoin', but bear in mind this coin will never be the BIGGEST, just the BEST.
