I'm the person who produced this video -- I just created an account to match the new Youtube channel name.
I don't recall any convincing arguments that Bitcoin was dead back then.
Hm, you're right. I had misread this thread as anti-bitcoin:
https://bitcointalk.org/index.php?topic=45977.0 However, it's clearly not. Opinions were mixed in late 2011, but there were no strong arguments that "bitcoin was dead." I stand corrected.
Watched the video. The video is not about the long term stability of bitcoin, it is actually an ad for peercoin. But it is very infomative, some points are a bit shaky, and I learnt a bit more about PoS. Enjoyed the video, but still not interested in peercoin.
I consider this to be a fair review. The video really is very pro-Peercoin, because it focuses on the potential risks in Bitcoin, but only briefly touches on the potential risks in Peercoin. If you are interested in other aspects of Proof of Stake, I recommend subscribing to the channel, as more videos are planned.
Thanks for watching!
