I will agree with Armstrong's skepticism on cryptocurrencies. We can even see that Bitcoin is becoming increasingly centralized (by design) and will be easily regulated by the international cooperation to hunt down all "tax cheaters" (which is a euphemism for "any one who doesn't agree to expropriation and slavery").
To subvert the tremendous flaws in cryptocurrency is going to be a monumental effort.
And then, can we prevent the bastards from filtering our packets?
Lots of technical hurdles and some may be insurmountable (but not if smart people get to work, but I don't see very many smart people really working on the issues and we are running out of time...looks rather hopeless).
IMPORTANT: Could someone please email Armstrong immediately and ask him to include some analysis of the Bitcoin price and potential bottom in his
upcoming precious metals report (private assets correlation)? Tell him many of us will buy the report if he does. We really need his computer model's analysis of Bitcoin's price.
