You can't buy Numeraire. It must be earned. Numerai via "Proof of Intelligence." First token with intellectual premium.

If you are buying Dentacoin, you are part of the problem.

Why will Bitcoin accrue value in a way that Ethereum won’t?

Because in addition to being a protocol, it is a product.

22 days until Monero has Ed25519 bulletproofs. But the real question is, how many days until a critical vulnerability arising from the naive repurposing of Ed25519 “ref10” arithmetic is discovered?

I am excited to see how zero knowledge cryptocurrencies like Zcash interact with the extant regulatory landscape. I think it’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.

I’m a big fan of 0x and decentralized exchange.

I’m also a big fan of enabling unique new things using this technology.

I’m not a big fan of pretending old school financial engineering is one of those unique new things.

Like Bitcoin before them, the assets that have met a real economic need have done so by enabling a form of ownership or transaction that was not previously possible. Zcash and Monero, which both implement privacy as a feature of transactions, are good examples of this.

Tether is kind of like USD, except instead of being backed by the United States government, it was created by a guy who fled the U.S. following allegations of raping children and who claims if he needs more money, he just invents a new token.

When Bitcoin Cash and Bitcoin SV get to mining cost equilibrium, assuming their prices are both $100, the cost to reorganize 6-blocks will be $7,500 (12.5 block reward with almost no fees x $100 x 6 blocks ). In 1.5 years that cost halves. Still think a fee market is ridiculous?

Interest has been low [in Bitcoin Gold]. That said, I think it's actually interesting. Likely to be hugely successful? Probably not.

I'm happy [to be] getting a free stake in their experiment [via hard fork] -- decentralization is important and they're trying a different angle to achieve that.

Plus I can appreciate that it's a non-hostile fork with strong two-way replay protection and isn't trying to take Bitcoin / BTC name.

Tezos is a remarkable project because it enables coin holders - the true owners of the network - to align interests around improving the protocol through on-chain governance. In 2018, Tezos is going to amaze everyone.

Bitcoin is something that is natural, decentralized, uncontrolled and digital. This is something that didn’t exist before Satoshi invented it in 2008 and I would argue, doesn’t exist with any other cryptocurrency. This is the key to Bitcoin’s usefulness as money. Scarcity is the first thing that’s required without which its proposition as money crumbles.

Bitmain is the central bank of BCH. Bitmain has tried to maintain a peg to their reserve currency, BTC, and has failed. Bitmain has failed to keep the peg at 0.15 BTC, 0.12 BTC and recently capitulated the 0.1 BTC level. This is a central bank selling its reserves to keep its peg to another currency. What’s worse, much like a central bank, they’re running out of reserves and BCH will finally float on the market instead of having the artificially inflated value that it has now.

[W]hat *are* people buying with Bitcoin that dwarfs its use in traditional e-commerce and on the dark web? Remarkably, the answer is something that DIDN’T EVEN EXIST when the Bitcoin paper was published and ONLY EXISTS NOW *because* it was published.

The answer is that, so far, the primary “commerce” use case emerging for Bitcoin is to buy *other digital assets*.

In just the last couple years, billions of dollars in purchases of digital assets have been made with Bitcoin (and Ethereum). . . . Bitcoin and the broader cryptocurrency ecosystem has giving rise to an emergent “commerce” use case that no one, including Satoshi, could have predicted.

Stellar is designed specifically for tokenizing assets, which anyone can do by being an anchor on the network. It has a built-in order book for decentralized asset exchange. Its consensus model, SCP, strikes the right balance between decentralization and trust.

Monero is less scalable [than Bitcoin] because you have to store all transaction outputs (key images) instead of just unspent transaction outputs, since Monero does not know which outputs are fully spent (for larger ring sizes). And these must all be stored in fast random access memory for double-spend prevention. That’s an ever-growing pile of data!

While in Bitcoin, you can offload older UXTOs to a slower memory, because the access pattern is “UXTOs die young.” Also, UXTO set grows much slower or even can be stable (“1 UXTO per person”) while transaction volume grows forever.

Bitcoin scales way better than Monero or Zcash (that has the same requirement to store all “nullifiers” to prevent double spending).

I worry that a lot of the proposed [technical stablecoin] implementations will appear stable… until they aren’t - a huge left-tail risk. In the Tether model, the failure point is known (counterparty risk). In risk mitigation, the devil you know is better than the one you don’t.

[T]he one and only litmus test [for whether a blockchain is truly decentralized] is whether you can fully control your money in the presence of many other people trying to control your money. Bitcoin is the only one that passes, by a large margin.

Sources of BTC demand in years ahead:
1) Generational shift (teenagers want crypto more than cash and gift cards)
2) Central banks and institutions (demand for non-sovereign digital asset with absolute scarcity)
3) Programmable money (the opportunities of natively digital money = HUGE)

PayPal helped bring money into a digital age by creating a digital front-end for legacy infrastructure but PayPal didnt create new infrastructure. Bitcoin and Ethereum *are* new financial infrastructure: Digital infrastructure for a digital era.

“Time-locked” and “multi-sig” transactions are two early examples of advanced functionality that is possible with programmable assets. They replace hours of legal time and cost with a couple lines of code.

Programmable money is finally here.
