Do you think it has won already?
Depends what you mean by that. Bitcoin already won against fiat from day one.
Needs more countries to adopt it as legal tender?
Do you know the definition of "legal tender" ? Bitcoin doesn't need to be legal tender in order to be used. Read here what really is Bitcoin. - seems that you don't know it yet.
Larger market cap?
That is the fiat maxi mentality talking... You are buying BTC to sell it later for fiat? Or you want to use it as money and get rid of all fiat, banksters and govs?
More usage?
For more you use BTC as money, stronger will be. For more you still use fiat as money, more time you will suffer in your debt slavery and tyranny. Is just a matter of time until more merchants will accept it. The question is: What did YOU do to push that adoption? Or you just wait to happen? Read more:

Don't wait for Bitcoin to win. Make it happen around you!

Great stuff! Thanks

Sovereign is not a language of the masses. That language has only three words: tap-swipe-click. It's the BTC/USD pair that will do the damage. The closer they get to coitus, the closer we get to entering the actual bend in the parabola. Embrace the dark side lord Vader.
