I often get asked privately if Bitcoin is worth an investment. My answer is a whopping yes
.invest your time.
The price fluctuation of Bitcoin is certainly fascinating, but how cryptocurrencies (and blockchain, more on that soon) will affect you, your job, your business, and humans collectively is far more lucrative.
The financial (and in turn, geopolitical) institutions are about to go through what the media (music, books, TV, newspapers, cinema) industry went through since the rise of social media during the past decade.
Your investment in time learning about blockchain uses will far outweigh the investing of your $ ¥ £ etc..
Obviously you should invest in Bitcoin the amount of time and money in that you are ready to lose and spend, because there is no guarantee that you will be beneficial and profitable from that. So it's like a hobby with your spending money on.
