Angelshares is a pretty kewl idea-- allowing angel-investing rather than spending the money mining Protoshares on electricity.
Really not sure about his anti-mining comments tho, as you could say mining is the very reason bitcoin keeps climbing in price, and that's been a boon for the whole crypto-marketplace. He'd also need to talk about security, as high difficulty mining creates a rather secure network from attack, whereas not so sure about BitShares, think we'd need to see it surive a rather nasty fall and another subsequent rise before we can fully trust it.
Been there, done that:
I laugh every time I see this chart... "The Great Nickel Depression"
good point on the price, but we mean a fall in security. Remember, bitcoin survived a fork where billions of bitcoins were created in the early early days. they forked to fix it. same with ether. has bitshares had one of those moments? We also mean a crypto-meltdown, we really don't consider ANYTHING in 2017 a crypto meltdown.
