I guess theres 3 parts to this post. 1. Do you know what they are? 2. Have you invested in any? 3. What are your thoughts? I have small holdings of bitcoin and litecoin. I accept that at this stage, being so early, cryptocurrencies are incredibly volatile and I'm comfortable with a complete loss, should it occur. However, I also see a potentially VERY bright future. Perhaps not from this first generation of cryptocurrencies, but certainly with future iterations. I think this is one of the most disruptive technologies to appear in the last century. Cryptocurrencies are to money as the internet was to communication. The third world is where I see the most potential up-side over the next 5-10 years. Time will tell. Until then, my seat belt is on and I'm enjoying the bumpy ride.
