One thing that’s interesting is that unlike Bitcoin, which was so maligned and ignored at launch that Satoshi had to mine by himself on a single Intel CPU for most of 2009, there is (by our conservative estimates) $100 million of mostly VC money invested into special-purpose investment vehicles to mine Grin. This does a lot of weird things: It turns a bunch of people who would have been buyers of Grin into sellers of it, it changes the composition of the early holder roster, and it means the chain will launch with an extremely high degree of security via high PoW hashrate.

Despite the big amount of professional investor interest in Grin, the community itself is the closest thing I’ve seen to how the early Bitcoin community felt. The lack of a premine does magic things to human psychology; when you are doing free work for something that someone else gave themselves a huge bag of, you feel like a chump! When you do free work for something that everyone has a fair chance to mine, you feel like you’re part of a tribe, and that effect is in full swing with Grin. Wallets, decentralized exchanges, stats pages, etc., are all popping up, and our Grin community channel has smart devs asking what they can build every day.

I don’t see how Grin can win if it’s not differentiated enough from Monero (both tech and community). Open to be proven wrong.

What makes Grin dangerous is that it does have a compelling story and people might think that translates into value for the coin. The user experience is shitty. To get even remotely close to Lightning, it would need years of work [and] hundreds of devs. It won't be used [in] real life.

If I were doing it all over again (like Grin is), I would probably choose just a fixed inflation rate, i.e., 1 ZEC per block from the genesis block until the end time. Grin has chosen that, and I'm envious of the simplicity.

If Grin is successful, it will be linearly inflationary and disempowered in a few key aspects. Imagine: Monero = crypto Swiss bank; Grin = confidential emailable cash transactions.

Imagine what a universally accessible, private, scalable and fungible digital coin could do. Since Grin’s introduction, its developers have enabled capabilities such as Lightning, Schnorr signatures, bulletproofs, Dandelion relay, “scriptless scripting,” and atomic swaps. All these greatly increase the probability of the Grin blockchain being able to address a multitude of use cases that have not been possible with the existing set of blockchains. At the very least, Grin coin may actually fulfill the promise of digital cash.

Grin is mostly a feature. That feature can be added/accessed via other cryptocurrencies without a new token. I think it's unlikely base protocols with new features can survive long-term.

Grin's reason to be is mostly mimblewimble, which is a feature, which I'm skeptical is enough to support long-term value for a base protocol cryptoasset.

[Mimblewimble] is amazing, which is why we’re building a Monero sidechain on it. Grin is excellent, and it’s doing great things that I’m personally quite excited about.

Grin has designed may be the most compelling meme after Bitcoin - "Time is Money."

The meme should convey a tangible, powerful and promising message. "Finance" is already a highly abstract concept, not mentioning "Defi"
