Banks and governments buying BTC may never be a world wide thing, there may be some governments that would hoard BTC for their own reasons we may never know of, but that number will be very small and of little importance. Think of it, with the problem of inflation and other critical economic problems plaguing many nations, most of them living in poverty and can't provide anything for their citizens, buying BTC should almost be off the cards for them.
But we don’t hold assurance of that, as most of the government officials are greedy and would want to take advantage on every asset that gains highly valuable, and bitcoin is not an exception. So we should not be totally carried away when they say avoid bitcoin because it will only put us into misery and debt, because the truth is those big whales in the crypto market are actually the big officials in the government that have invested huge amount for their own satisfying profits.Yes, there is no guarantee what they say is true, people being poor doesn't mean the government will be poor too, I have never seen a poor government, even if it is a default country. Don't believe what we see from them, they are human too, what we see from bitcoin, they will also see, the potential of bitcoin is impossible to hide.
I am not sure if the whales in the market are government officials, but I also believe that there are some governments that are banning their people from buying bitcoins, but they are still sneaking to own bitcoins. Bitcoin is a valuable asset like gold, so they won't ignore it. Also, it's anonymous, so we can't assume they won't buy it.
