That definitely seems good. But we'll see if he'll stay true to his words. If he's honest, it's a great new beginning for the country and the whole crypto industry.

According to my Nigerian time zone, I was alated with the notification of the Argentina new president, however, I confirmed that the new president is also a Bitcoin lover.

The link above will tell how the citizens of the Argentina country loves their new president, although I can't really tell if they like their president based on he is a Bitcoin lover.
Gradually gradually, Bitcoin is moving at a good speed and also spreading.

OP I think this topic will best fit in Politics and Society so you can try moving the topic there.

However, it's a good thing that most countries government officials are willing to embrace cryptocurrency. Perhaps they have seen and believe in the new technology. Very soon we will be hearing news about Bitcoin campaign and rallies in Argentina and many of the citizens will begin to accept Bitcoin and at last may be accepted as a means of exchange in their country.

It will be interesting to other prominent people in the society to embrace bitcoin in the society, and secondly what I will want the new elected president to do concerning cryptocurrency is to ensure that it has make a bitcoin a legal tender since is a lover of bitcoin despite that the legalisation of bitcoin has to be pass it into law, because if it happens to me I will ensure that I have legalised bitcoin, so bitcoin will have more dominance again across the world.

Congratulations to his victory but the politicians are definitely not a solid wall to lean on as there sugarcoated words are dearly to attract personal interests favour from the masses at the time of electoral campaigns.
And if only these Political alleys could have exhibit are promised during its campaigns, the then they could be reliable.
However, with benefit of doubts, there is set to be a massive excelling as this course that is to tender global enhancements with an authorized massive adoptions and a wide spread of Bitcoin through his regimes in government.

We will have to wait and see how much importance Argentina's president-elect places on Bitcoin. But I think the legal tender clause would only be appropriate if it declares bitcoin legal, as Argentina has a large number of bitcoin/crypto holders.  
As has been done by El Salvador's President, Nayib Bukele, he has accepted Bitcoin and declared Bitcoin legal following all principles of legal tender. And he has bought many bitcoins which will protect him from future financial storms. Because Bitcoin is the most suitable way to invest for a long time, because Bitcoin will definitely have high speed with its own speed. El Salvador's Volcano Energy is generating energy.

When I watched to their presidential election debate, I noticed he has a lot of similarities with former president of the US. He was vocal about his plans and visions and seems determine to do just like he said. He challenged the financial systems and promised to embark on several reforms that will change the status quo including the central banking system.

But I see a little problem in all of them. Will he have the political will to challenge the powers that be? Argentina is not that of a strong country and they have a lot of unsettle businesses with IMF, can Javier Milei withstand the pressure from these powerful organisations?

As for the future of Bitcoin in Argentina, the new administration will most likely legalise Bitcoin just like El Salvador did but I don't think they will see the benefits immediately because they have a lot to address ranging from unemployment, inflation and poverty.

President being crypto-friendly doesn't mean it will be positive news for the whole crypto market.
Let's note that there are still other authorities that are against crypto and might stop making some regulations.

I did a quick search and based on this website, the total percent of the population that is currently holding Bitcoin this 2023 is only 5%. Well, it's in the top 15 for the highest number of population who own Bitcoin. With the new president that's pro-crypto, I expect it to go even higher. I don't know if this will have an effect on the price of Bitcoin, but let's just not overreact with this one as we don't know what the newly-elected president will do.

There might be a chance that he just used cryptocurrency to increase his popularity. I mean they're politicians, and I'm not generalizing all of them, but there's a "CHANCE".

That is very good News and I believe is going to win the election in Argentina as a president, which is going to create a good impact or add more advantage in the cryptocurrency space adoption.

If what is being said is accurate, this is fantastic news because politicians in general cannot be trusted, that is how they will make promises when proposing. And, after winning or obtaining the desired position, they will promptly forget all past pledges. If he keeps his word, I believe it will make all their country happy and also proud him. And once more, it would be amazing if he acknowledges Bitcoin as legitimate money, which would lead to an increase in the number of Bitcoin users.
