Why 5-10 years? Hype cycle, or do you think there will be changes in the tech that could make it useful to these institutions at that point?
I focus on Ethereum just because it's the center of innovation in crypto nowadays. Bitcoin has only incrementally changed its software throughout the years and only gains more use as a store-of-value as demand for it increases (hype cycle). After a bull market run it generally takes 5-10 years to reach its peak again.
Bitcoin has only existed for 14 years—seems a bit early to generalize anything based on the two times it has peaked and crashed so far.
On almost every dimension Ethereum looks like the most decentralized network out there: Most nodes, most validators, most distribution of validators, most clients, most development teams, ease of making your own block.
