Save it from becoming completely meaningless in terms of challenging the legacy banking system, which is the main reason crypto was invented.
Sometimes scams can be turned around to scam the scammers. If Russia and the BRICS were to allow certain cryptocurrencies as means of cross-border payment, all of a sudden people have an off-ramp for USD assets as the USD starts to properly submerge in the flushing western economic toilet. All that wealth that the PTB thought they were going to "liquidate", suddenly transferred to jurisdictions outside their control... sure, it might not affect their plans for CBDCs, but helps keep wealth in the hands of the common folk, which is really the whole point of the system.
Well, interestingly, the catalyst for FTX collapse in the end was CZ, a Chinese dude. He called out FTX, exposed it as a house of cards made up of nothing but a bunch of shitty IOUs, showed that Sam was sitting on nothing but vapour. And CZ's whole schtick throughout this has been "funds are safu", proof of reverses etc. I.E. It's backed, we have what we say we have. Now I can't vouch for that being true, but it gets interesting here.
This situation is an analogue of exactly what's currently playing out on the global stage, and might even be giving us a fractal lead on what happens next. FTX being the West and Binance being the BRICs. What else is a house of cards based on IOUs? The entire Western financial system. And what are the BRICS attempting to do? Hold real assets, commodities.
Bear in mind that Binance has been hurt pretty bad by the collapse too, along with anyone holding crypto tokens. Not just that but now no exchange is trustworthy, and there's almost no way to even short it safely. Even if you make an accurate bet on it going down, you can simply be rugged by your counterparty. So the whole system has been badly damaged. This will likely be the same on the global scale too. Nowhere is safe other than your cold wallet ( = the gold coins you have buried).
Now will crypto as we know it play a role globally in future? I have no idea. But given that Satoshi Nakamoto roughly translates to "Central Intelligence", that crypto has only ever been a speculative asset bubble propped up by endless easy money printing pushing people further down the risk curve, that the space is full of scammers and degenerates, and that there's likely regulatory clampdown coming? Well, it's probably not the best place to store a lot of money now.
