States holding such a big amount could interfere too much into Bitcoin's power equilibrium.
Thank Goodness you raised this topic was starting to think like didn't no one notice it. infact emphasis of that statement being In bold.
Bitcoin is a decentralised currency yeah we all know but let's not forget the fact that the decentralisation of the bitcoin network is based on majority.
Starting from mining which runs on a 51% rule to fees which is dependent on average transaction fees in that block to even then whole bitcoin price which depends on selling and buying rates that in turn is dependent on major holders and whales.
Take for example Bitcion crossing over $70k with bitcioners cheering about it then boom the German incident happened and since then bitcoin has been struggling back to $70k which was almost a new low.
The fact is what really can anyone do???
The only thing is bitcioners can try to hold as much as they can hopefully the government doesn't get hold of enough coins to violently shake the market.
