I note that the Ethereum Foundation being in Swiss jurisdiction is meaningless, when the U.S. could throw the whole Ethereum ecosystem into turmoil simply by shutting down ConsenSys. Whereas Bitcoin does not even have a centralized foundation, let alone any centralized critical infrastructure run by companies amenable to enforcement actions. Bitcoin’s past experiment with a centralized foundation taught it lessons that Ethereum never learned; and it doesn’t really have any critical centralized infrastructure at all.
The US authorities can destroy any cryptocurrency and the entire ecosystem, but there are also many people in the US who are lobbying for cryptocurrencies. I believe that bitcoin and ethereum are big ecosystem assets that have huge lobbies in the US, and these projects will not have regulatory issues as long as the big bosses need it.
