I have been on the Bitcoin train since the price was about $30 in 2013 and watched the infamous Mt-Gox $1,000 bubble in 2013 only to crash after that.
Somehow I now feel this will not happen again, there will possibly be a correction depending on what China does this year but we will never see the kind of volatility we have seen in the past unless the internet breaks or is broken!!
Its the shape of the future as far as I can see and with countries already scrapping big cash notes we are already on the road to a cashless future.

Bitcoin has outperformed all currencies for the past 3 years by a significant margin and hopefully 2017 will be the year it breaks out of the early adoption curve into the early majority phase. http://www.blocklink.info/
For those wishing to learn more about Bitcoin from a passionate believer who sold his house to travel the world and deliver talks on Bitcoin after the Greek Financial collapse, see here for some YouTube videos. https://antonopoulos.com/
I use it for online purchasing and mainly for digital audio downloads and the rest I have sitting accumulating value.
The best advice you can get from anyone into Bitcoin is to never buy more than you are prepared to loose.
