He has always been hard on bitshares and has tried several times to stump dan with difficult questions on ltb with little effect. Much of it comes imho from early days when bts community didnt want to pay for advertising during ltb hayday...and maybe some other stuff with dan and him. Regardless, andreas though a very nice guy really messes up by ignoring bts and this tech.
And lets facr it, if we are talking about his main argument that nothing out there has what bitcoin has today...is wrong. Steem backed dollars, with steem at ethereums marketcap and volume, would be be easily as good if not better for onboarding everyday, noncrypto people.
I cannot tell you how many people I have met here who were introduced to crypto by steem...
He should just say "I am sorry but I do not have deep enough understanding to be qualified to give anything but a my thoughts in general about blockchain-driven social media networks." Or simply "Im not qualified to answeryour question at this moment."
