I haven’t heard any rumour of this happening. It would help if you added a links to articles where it was published. Still, I wouldn’t put it past the Saudis government, they are very prudent with money. In the last few years, they have invested heavily in sports - football and boxing. And have brought major attractions to their country. The only challenge I can think of is their religious belief, I read somewhere that it’s frowned upon for a Muslim to own Bitcoin.
