That's a good question. I take that to mean whether or not some cryptocurrency can become a global reserve currency and the dominant currency of transnational payments in the future. The US dollar serves as a global reserve currency at the moment. Central banks all over the world hold it as part of their reserve along with gold.
I think it is possible for Bitcoin to become a global reserve currency eventually. But it will require that the US and its dollar lose their current hegemony. I'd say it is bound to happen once the constantly declining US share of global GDP becomes low enough. It's on a downtrend of about 0.25 percentage points per year. If adoption of Bitcoin as a store of value grows sufficiently, I can imagine central banks accepting digital assets such as BTC as part of the basket of commodities in their reserve along with gold. That will require the market cap of Bitcoin to grow by several orders of magnitude. Also, its mining would have to become truly decentralized and global. Right now, it's concentrated in China a bit too much.
Most cryptocurrencies are quite immature at this point. Their adoption as widely used payment systems requires substantial improvements in wallet software and also custodial arrangements.
