Bitcoin has unfortunately innovated more lowly than Yahoo in the last 10 years. It may end up the reserve e-gold, but the conservatism that has prevented evolution of the tech may ultimately even threaten that status.

I would be long Bitcoin, and neutral to skeptical of just about everything else at this point with a few possible exceptions. There will be one online equivalent to gold, and the one you'd bet on would be the biggest.

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.

Ethereum is sucking the wind out of every other coin's sales.

I have a positive impression of the Litecoin community, but I'm not optimistic about LTC's future.

Nano is looking to be for cheap, simple payments. It's not trying to be maximally decentralized like Bitcoin. It's arguable that, even if only data centers ran historical nodes, Nano would be less centralized than BTC, whose hash power is controlled by only a few pools.

Monero is considered the gold standard among private coins largely because it started with domain experts in privacy who took all the right steps in the formation and design choices for a private coin.

Everything that Dash provides can be built as an application on top of Bitcoin. Never needed to be baked into the blockchain. IMO it was a premature engineering decision.

There are ways to be so unproductive it's better not to contribute. Privacy is like medicine or building bridges: someone can get hurt if you do it wrong or mislead.

Trust me, Verge is not helping anybody but themselves.

IOTA, made by the same geniuses who rolled their own cryptography without peer review, harassed the cryptographers who found the vulnerability, and tried to cover it all up with increasingly absurd excuses.

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.

Bitcoin Cash is like the dysfunctional, bizarro version of Bitcoin.
- A known fraud is the figurehead
- The intended form of protocol governance is by miners
- Their primary form of outreach is propaganda / brand confusion
- Their origin story is literally a conspiracy theory

Bitcoin Gold has some of the most irresponsible/incompetent developers in all of crypto. They delegated the security entirely to 3rd party wallets, some of which stole millions and others with a history of selective scamming. They never fixed this and have no plans to.

I'm really curious to see how the "utility tokens" turn out. I suspect they'll be pennies on the dollar. The tokens of CVC, for example, are gift cards for using the service. I don't think there will be enough business generated to justify $223M market cap.

Ravencoin should not exist. Doesn't need to be a coin and probably not great at stopping ASIC development. $150m market cap is absurd.

In regards to privacy, XMR, ZEC and GRIN are the only good options. Zcoin protocol may be ok in narrow circumstances, but some privacy isn't much better than no privacy in general. The common theme is the use of zero knowledge cryptography.

The more new chains launch with massive issues (including some with huge budgets) the more impressive it is that bitcoin has never had any similar catastrophes, over a much longer period.

Ethereum would have been better off supporting applications that were banned from web 2.0 rather than trying to be "web 3.0."
