    [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.

    I love the Grin developers and fully applaud what they’re doing, but let’s not overstate claims as to privacy. MWs primary goal is scalability, not non-interactive privacy.

I’m supportive of Decred’s efforts to add privacy, because there are actual development chops there, and Decred doesn’t appear overly scammy.

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.
