The recent price action of cryptocurrencies has grabbed the attention of the mainstream media and speculators. Talk of returns of hundreds and even thousands of percent in a short space of time is hard to ignore.

The reason I stay in cryptocurrencies is the fundamentals. The price may go up and down daily - often large swings - but the fundamental story behind blockchain is solid. There are many, many news stories about the underlying technology of these currencies - and the overwhelming majority of reporting is positive on the long term prospects.
