I will never stop hodo and buying Bitcoin. The price doesn't matter when you ride the volitility to Bitcoin riches. I'll be buying Bitcoin untill I can generate lots if it by myself. Then time to retire. 
Yes that is the right thing to do as bitcoin has a great potential to give us huge profits in future so we should keep on investing our money in it irrespective of the price and as of now I believe that bitcoin is the best investment to make so will continue to buy them till I have excess money.
