It's a good idea not to take a risk and just hold your bitcoins, becuase you will never lose your money if you are attentive enough, i believe on you 
with bitcoin if you hold it it is impossible to lose your money because in a longer run the bitcoin price is going to reach a new all time highIf you believe in holding it for a long term then you don't have to worry about your investments, as price will surely go higher in future which will help you in earning higher profits.
Yeah and even if you cannot hold it for long term even though this is not the perfect time to sell your coins as price is below $600 mark and not the best price to earn good profits.
