    I think PIVX is better [than Zcoin] for Zerocoin implementation. It uses the same libraries, but with Proof-of-Stake. But industrial-strength privacy is still Zcash and Monero.

    PIVX is interesting because it is proof of stake, meaning it will be very cheap to always send transactions with the Zerocoin protocol. A great balance of privacy and convenience.

    PIVX is a great project. They have a great balance of convenience and privacy. But when we're talking about protecting government targets, mixing when convenient isn't a good idea. Transaction amounts are still visible. Blockchain analysis is possible.

The problem is I don't think XRP has a use case. Currently its intended use case is highly speculative, yet unproven. Banks are still uninterested in the token XRP six years after Ripple was incorporated. Banks are not clueless.

The biggest competitors for LTC and BCH? Stellar and RaiBlocks. These coins were architected for payments that provide low / zero fees, high throughput, and fast confirmation. They provide these solutions today, and there are no hidden tricks like subsidizing transactions.

IOTA is disputing this in part because

- they lack a functional understanding of cryptography to the extent that they are taking the informal answers of as rigorous definitions;

- they lack any natural intuition about how to think about security, to the extent that they are rolling their own crypto and testing it on production systems without peer review; and

- they lack the social skills to accurately interpret the more qualitative aspects of these textbook definitions, such as what the word โ€œnegligibleโ€ means.

An exploit existed [in PIVX], and it was patched. [PIVX's] handling of this (i.e., denying it had any potential payload) is VERY telling about the calibre of project you're involved in. And, thusly, PIVX went down several notches in my eyes tonight.

PIVX has both an active development team and a community dedicated to improving the coin for all users.

PIVX master nodes are unwinding โ€“ people losing faith. If they start to liquidate (already happening on PIVX)... the cascade will be something to behold.
