Because we all accept a different level of risks. Some are more high risk taker, and some are low risk taker.

I personally is a high risk taker by nature. I like playing with dangerous extreme sports, and I deal with Bitcoin the same way.

I think Cointerra, Black Arrow and KNC are what I will bet on. I personally got a few KNC and already pre-order the next gen KNC product.

Cointerra and Black Arrow looks good. But due to the fact I am in the UK. All EU import doesn't have import tax. That is why I go for KNC.

So if you are in the US then Cointerra is the one I go for.
