Yes There is always A risk . No Risk No Gain . Same Thing Applies here .
What i can suggest You is to Monitor Your Btc Portfolio On every Week Basis and have some stop Loss Limit fixed and You can divest your amount when It reaches your stop loss Limit . This way You Will be Minimizing Your Risk .
I agree, and to add to that, the higher the risk, the highest the return! That's basically how it is. The more risky your investment then the higher the returns. Look at the first adopters of bitcoins have profited so much. They risked believing in something and now they are filthy rich! Especially those people who had thousands of bitcoins when the prices were just a fraction of a cent each.
