The interesting question is of course here if Bitcoin can eventually fulfill the role of a "safe haven". I think most agree currently it seems to not be one. Volatility is still to high even if it's
declining over time, and above all people are still very scared of crashes and dips. The long term bullish tendency is there but it could break eventually.
The crucial idea here is to take away risks which currently impede Bitcoin's stabilization.
My take again is that it could be a safe haven if it was used slightly differently: first, it should be better distributed, and second, it should be used in less speculative ways.
Better distribution would make it unfeasible for governments to ban it or regulate it too harshly, and that takes away one of the biggest risks for Bitcoin's price. Who would dare to ban Bitcoin if let's say 15 or 20% of your population uses it, and you depend on their votes? Some countries already achieved that mark.
A really well usable 2nd layer, be it an improvement on Lightning or a sidechain, would enormously help with distribution. With on-chain activity only, there's a bottleneck for onboarding much more people, and I guess that many of the ~300 million Bitcoin users today are using it via custodial wallets or simply hodling/trading on a CEX.
Regarding speculative usage, HODL & DCA is already better than "trying to ride the bullish waves". But the best, most stabilizing kind of usage is the usage as a currency.
At the same time, I do not rule out that Bitcoin is more decentralized than it seems. It is quite possible that the Chinese Communist Party has found some secret way to secretly mine Bitcoin. North Korea and rich Arab states are probably mining Bitcoin as well.
Just according to Hashrate Index,
around 20% of the mining power still comes from China. They used to hide as "German" nodes in older stats (because Germany is a hub for VPNs) but in the Hashrate Index map it seems to identify them correctly. I also think that 35% of the mining power located in the US is still not problematic, if there was a problem the consequences would be less harsh than what we already experienced in 2021's "China ban".
