Bitcoin is, regardless of what anyone tells you, 100% speculative in nature.
As an immature, illiquid, and low volume market it can be manipulated quite easily which creates lots of unpredictable volatility.
I am a fan of bitcoin, this is why I am here, but as investments go it is essentially ultra high risk, and should only be funded with risk capital.
My opinion; buy BTC with 10% of your available high risk capital, put 20 to 30% in another medium to high risk fund, as your young you can afford some mid term volatility, and the rest should be in something low risk or tangible.
