Even though I do not have a humiliation fetish, I'll give this a go, but I'm not answering the questions exactly because I don't want the money.
The year is 2022, China becomes increasingly more and more worried about Bitcoin providing an alternative to the Yuan for its people, but in this new theoretical timeline, the CCP offers tax incentives to Bitcoin miners and builds a ton of renewables to provide cheap electricity.
The plan works and more than 51% of all Bitcoin mining power is within Chinese territories. The CCP acts, raids all the mining facilities and forces them to collude under threat of jail time.
The miners collude to force the network to double spend on a single 0.5 BTC transaction.
They leak the double-spend, or don't and wait until someone else finds it. The world freaks out that double-spending BTC is possible, panics and there is a run on Bitcoin because everyone is worried that their funds are next.
The CCP successful creates doubt in the Bitcoin network and as a result it's no longer a threat to the Yuan.
I know it's not exactly following your question format, and this idea isn't mine, I just remember reading someone's blog about it.
