I have the confidence that bitcoin will not be the market leader in the near future. The leader will be more technological cryptocurrency.
Concerning the national cryptocurrency, they will be regulated and will be successful, only within each individual country
So, you're confident that a cryptocurrency that doesn't exist yet will take over, and it's going to happen in the near future
Good joke.
The reality is that BTC is paving the way for all the other altcoins. If it fails somehow, starts looking like a fad, the altcoins will take an even greater hit.
As for the decentralized vs centralized cryptos, I believe that decentralization will win. We just need people to realize that everything the government touches turns to shit.
There will be another wave of the financial crisis and another (yes, wave, because we are still in a crisis), and finally they will have to open their eyes.
