I would like to share the following clip on cryptocurrencies and bitcoin in particular from Jim Rickards on Kitco.

Highlights:

• Bitcoin is money and not an investment
• Bitcoin may be in a bubble
• Beware of possible regulation changes

Questions for the community:

1. There are great commentaries on gold/silver vs cryptocurrencies on YouTube and Steemit but I am seeing a trend of increasing competition arising from the 2 camps. Do you think this may be a generational bias, the majority of boomers prefer gold/silver, while millennials prefer cryptocurrencies and GenX is in between. Does anyone have any thoughts on this?
2. Loss of US dollar confidence would see an increase of gold and silver prices as well, but if gold and silver prices are manipulated via ETFs etc., could this statement be false?
