I didn't launch mine, nor participate in his (obviously). I suggested that a business in that space, if successful, would result in a similar outcome as happened to other founders of international money transmission systems that weren't under direct government control: i.e. swatting.
He was not dissuaded, to his credit. Score one for the "founders must have grit" camp.
To be honest, I'm still not sure why the hammer hasn't come down on something like Coinbase by now. It seems that cryptocurrencies in general are the exact opposite of the regime outlined by the BSA, PATRIOT, et c. My unsubstantiated theory is that it has something to do with pmarca, but that's just a guess. The founder of Kraken has expressed his feelings that it's coming soon.
I'm glad that Coinbase has permitted so many to participate in the ecosystem, but I wonder about how much of a benefit heavily regulated, custodial wallets bring to the ecosystem as a whole. It seems to me that Bitcoin existed to replace banks, and here we have a bank serving as the Bitcoin equivalent of gmail, re-centralizing everything in a place that is easily and instantly censored by the exact system it was built to replace. The fact that they're listed on a stock exchange and not as an ERC-20 or other permissionless token tells the whole story, in my view.
I have a special respect for those who can function in heavily regulated, guilty-until-proven-innocent style markets like financial services in the USA. I personally would not be able to handle it.
