That is absolutely right. When you guys invest, never ever set an expectation or set of expectations. Expectations are only sources of disappointments and frustrations in the end. If the investment went profitable, you have all the reason to celebrate and be grateful for it. However, if the investment went bad and your investment turned to zero, you will not be totally broken as to contemplate of more negative things to happen.

I believe that bitcoin is the least risky investment compared to many other altcoins. The only thing that bitcoin-investor may need is patience. If you have patience, then your expectation will be rewarded.
