    The reality is bleeding-edge crypto is risky; the counterfeiting vulnerability is the second inflation bug that Zcash has had.

    BTC has categorically worse privacy than ZEC on L1,, but the trade-off is a safer system re: total loss. Had this been exploited, it could have easily been a loss of hundreds of millions of dollars.

    On BTC, an inflation bug is very likely to get caught quickly, even if exploited, because of the transparency. There might be a few days shutdown at worse: awful but survivable even in the worst case.

    Not the only trusted setup-related issue that's been ignored by the Zcash team: the build process broke a month after the ceremony, and Zcash has been ignoring patches to fix even these basic issues.

    Highly suspicious that they have zero interest in people auditing the trusted setup.

IOTA is so batshit crazy they managed to turn a theoretical one-time-signature vulnerability into an actual, practical-to-exploit one.

"**Yes, the top 0.2% owns over 90% of the tokenโ€™s total supply.** This is more than double BTCโ€™s wealth concentration." (bolded in the article)

So? Tether is a tool to move USD around between exchanges. Why is it bad that a small number of exchanges mainly use this tool?

Hopefully, other exchanges do the ethical thing, too.

From a non-TA perspective, Zcash stands out to be the most robust PoW - secure against "consensus attack." And if you look at the 51% attack cost to market-cap ratio, it's substantially more secure than the anything else on this sphere.

I am excited to see how zero knowledge cryptocurrencies like Zcash interact with the extant regulatory landscape. I think itโ€™s important to remember that these techniques provide privacy that (IMO) is a *requirement* for a *business* use case..... With zero-knowledge proofs, privacy and transparency are very much compatible. You can prove properties of transaction flows in zero knowledge.

The condition under which criticism makes sense is simple: someone responsible for 50% of the operating Zcash nodes received $0 a month from the founder's reward, and someone responsible for a great many drunken tweets and awful ideas received $300k a month.
