Bitcoin has been confirmed as the best safe haven currency in the world
I think not. The only safe haven currency are stable coins. These are usdt, usdc, TUSD and many more. If you will hold bitcoin it will not be a safe haven to you as the price of it might go up and down. If it goes up, then it's good it's better than safe haven. But it goes down, that's worse than it.
Despite the fact that some of the people may not consider stablecoin as crypto when actually it is but kinda centralized but I'd agree that stablecoin still remains to be the best way to save your wealth value. They are backed up with money under certain regulation by the government and issued by the third party company, there's no argue for that.
