The US primarily holds seized Bitcoin and some Ethereum. There are no seized holdings of solana, ripple, and cardano. The crypto strategic reserve is mainly btc and eth. The rest were just mentioned to pump those assets and have their insider reap gains I think...
It was all plan because look I remember the second tweets about the reserve. This was the tweet.
https://x.com/trump_repost/status/1896247384923050059I don't know even know why he didn't specifically gives the attention to Bitcoin, he clearly mentioned altcoins first and them comes back to do ETH and Bitcoin. It should have been in order like how big they are in the market but it was random. If it was him that such thing is presented to, you would have heard him say "it's disrespectful to order things that way". He loves saying that and loves to criticise people but he does not want other people to criticise him for wrong doings.
The executive order has been signed, what next? Buy Bitcoin is what everyone is expecting but I wouldn't want to lie to my self, we will be seeing more speculations than the US buying more Bitcoin. I don't even want to know why seize Bitcoin are to be strategic reserve but it's understandable, something worth money and seize becomes governments property and wait when they have plans to sell like they used to sell back then, even Germany sold everything.
