Selling bitcoin at this price does look like a good idea, not sure if that's a bad thing or not. I get that some people may consider this bad, because lets be honest UK is mismanaging their funds, but bitcoin was never a good thing for the governments.
IMF is very against it, look at El Salvador, they are saying it is not even legal tender there anymore, because governments realize, they can't just put money aside, they are spending way too much, and saving is not ta thing they do. I know we all wish they did, but they spend more than they earn, hence they print money, so in a situation like that, saving aside makes no sense. They need to sell all they have, in order to tell people they need more, otherwise, if they have billions aside, you can't tax people more, they will just tell the government to sell more.
I think government want to make this Bitcoin to dollars because they want to establish their economy because dollar is their currency and they know that Bitcoin is best cryptocurrency but now they are taking this step to hold the money because when government will be change then these assets will go to the next government and they will handle this and will take the credit and present government is very selfish and they will think about their profit but if these Bitcoin will be hold by that government then they could be super power in the next 10 years .Now currency power of every country depends upon the government and politics because politicians are making effort and they are handling the Bitcoin.
