A wise country or government can sometimes be deceptive. China may be vocal on being against bitcoin and show to the world that they will never adopt bitcoin at all cost, but hey, we don't know what's actually happening under the table. Their transparency towards their citizens, towards us watching China is never that high, so there are still a lot of things that they chose not to become visible by us, and maybe one of it is silently hoarding bitcoin. And if they are actually doing that, so what? The rest are already adopting bitcoin, and for sure they don't want to be left behind.
I think they don't mind being public about their gold hoarding and letting the world know their true intentions, there's no reason for them to hide their bitcoin hoarding. Because so far, bitcoin is still just a speculative asset with a fairly small capitalization compared to gold. That means there is still risk and its future is unclear, whether it will become a safe haven or remain a speculative asset. If it were just a speculative asset, the government would not need it.
It is clear that China does not take bitcoin seriously and care, we do not need to come up with hundreds of conspiracy theories that they are secretly accumulating it.
In the eyes of governments, central banks still do not take bitcoin seriously, that is the truth and we need to accept the reality. Fed, ECB, BoE, BoJ or SNB, global central banks still have no intention of adding BTC to their reserves. PBOC will not rush into this race.
