Additionally, Ethereum ignored years of prior discussion regarding the safety issues of high-power scripts, and as a result of this and other design decisions, it faces serious security and scaling issues which have really started to become apparent as people try to actually use ETH for real applications. I can't see it surviving without major breaking changes or (more likely) an ever-increasing number of centralization band-aids.
Score: 1
I'm surprised you gave Ethereum a "1" given that its proposed PoS and/or sharding solutions are, at this point, vapor ware. It's purely a gamble long term because its solutions are unproven, even on paper.
Its method of anonymization has very severe scaling downsides, however; Monero makes Bitcoin look Visa-scale.
This seems to be the major downside of Zcash as well -- which might be why they didn't make anonymous transactions mandatory. The result of that, though, is that it isn't very private. Very curious to see what Tumblebit brings to Bitcoin....
Definitely curious to see your evaluation of other privacy-minded coins. That definitely seems to be the biggest obstacle for Bitcoin and cryptocurrency in general.
