Numerous people present detailed technical concerns, and the only response is "I am aware of the issues, I believe it will work". That and he deletes posts he doesn't like. Sigh
And given he's put in 1,222BTC himself, you have to wonder if some of the other payments aren't his also. I don't believe he's scamming, but I think he's now committed himself so deeply that even if it's clear he is wrong, he won't back out. Such is the power of the ego sadly. It does seem he's not got a deep understanding of market/finance fundamentals. The censorship is also worrying. If people are being offensive and swearing etc, that is different, but to censor people's posts because they don't agree is bordering evil.
