^ Because it's "US-made", that would be the answer for me 

It's surprising, unexpected as anything almost never thought of prior to this time that Donald Trump would choose altcoins over bitcoin in his strategic reserve  move is near betrayal to the bitcoin community.

But why SOL, ADA or even an XRP reserve? Well it's obvious these altcoins has in one way another some connection to America and it's like Trump is personal on prioritizing American projects in the Reserve. XRP for instance is owned by an American tech company known as Ripple Labs. Perhaps my suspicion may not shade much rationale light but it's something to keep track on.

I do think they are on the list due to them being US-made, so to speak.

Especially XRP, which is going as far as to do anything so that BTC reserves wouldn't be pushed as hard as their ones (which is a shame).

Not only that, both SOL and XRP are highly centralized for different reason. SOL require enterprise-level hardware/internet to run validator node[1], while XRP uses proof of authority (PoA) mechanism[2]. Although we shall see percentage of money will be used to buy those altcoins.

This tweet generated significant interest. Trump claims crypto industry has faced unfair attacks from Biden Administration and this reserve aims to boost industry. Inclusion of XRP Solana and Cardano might be surprising to some as many expected Bitcoin to be foundation of any federal digital asset holdings.
However Trump decision shows broader approach to blockchain adoption. Following announcement XRP surged 20% Cardano rose 30% and Solana increased by 15% potentially paving way for significant legislative changes including crypto friendly tax policies and regulatory updates.

The POTUS is just a big time whale manipulating the cryptocurrency markets strategically in order to earn huge profits for himself and the dumdums who follow him plain and simple.

It's ironic seeing his braindead supporters support him through thick and thin while he leeches off of them and everyone else in this manner. Toxic reality indeed.

The strategic reserve can start with seized coins but later by assessment, if this strategic reserve works fine, the USA will possibly consider to DCA cryptocurrencies to expand its national strategic reserve.

If Bhutan, El Salvador which are small countries can do it and succeed, the USA can do it and even do it better. They are a bigger nation, with much considerable more money to spend, and effects from their news are big already, so their actual action in accumulation can bring bigger impacts on this market, capital inflow and surely price will be benefited.

Did he refuse and announce it officially that he won't add Bitcoin to this strategic reserve?

He did not say anything like this and there is space and chance for his announcement on Bitcoin and Ethereum in future. He knows very well about news impact so he knows what he does with his announcement. We only are unsure about his thinking on Bitcoin and Ethereum, and whether he actually wants to have Bitcoin and Ethereum for the strategic reserve. I believe he wants them and only did not announce it yet.

If that's where this is heading, then the announcement isn't really that big since the U.S. isn’t actually risking anything. All they did was seize funds through law enforcement, then convert them into reserves instead of selling them off, like what the UK did.

It would have been more impactful if they actively bought Bitcoin, showing real commitment. But maybe that’s just how the market reacts -- once people hear the words "Crypto Strategic Reserve," the automatic assumption is that Bitcoin is going to the moon.

There will probably be another announcement today, as has just been posted in a Telegram channel for “Insider Trading News”:

Possibly the White House detailing yesterday's announcement? Personally, for example, I would like to know how high the proportion of altcoins in this portfolio will be...
So far, it's all very vague and I'm honestly surprised that the market has reacted so positively even though nothing concrete has been decided. It almost looks like 2017 is back, where "I found Bitcoin in the Amazon search!!!!" was enough for a x5.
