The reason crypto is still considered high risk investment (and should be for portfolio building purposes) is because the technology is still in very early stages, some of these coins are basically nothing more than white paper promises. Even on the bitcoin github it still says "Bitcoin is an experimental digital currency".

This is the reason I believe Bitcoin is increasing in price, the longer it operates without compromise the more it has proven itself the less risky it becomes. Most coins have not proven anything and if recent events in the security scene has shown us anything it is just a matter of time before the weaker coins fail to security flaws (we have seen this already).

The bubble talk should only be for short term traders. I am not concerned with bubble talk at all. In 10 years this will be nothing more than a little blip on graph.
