Back then, we only had Bukele (president of El salvador) as the national leader that was actively and loudly pushing for crypto adaption. Then Trump followed and now we have so many candidates for presidency and already presidents pushing for bitcoin. I think that this is a testament to how much bitcoin has grown that not only your average citizens know and use bitcoin but also presidents.
Regarding this, i still believe that Nayib Bukele still stand as the leader of them all, because he first move for the adoption of bitcoin and there is no other country that has been progressive with bitcoin adoption and legal tender as they have achieved, though the impact of Trump and the likes of bitcoin ETF have also helped in the market pump and push for more adoption, but El-Salvador still remained a unique significance to the entire world to follow their footsteps when it comes to bitcoin adoption.
Bitcoin mass adaption might come a lot sooner than everyone initially thought.
I think this is already happening except we are not aware of it, if you look into the bitcoin network and how its adoption rate has increased from the previous, then you will observed that many things have led to the massive increase and this still continues.
