Normally I'm buying bitcoins because its profitable and also nice to buy them because you know its profitable and has a good future a head these days, I think that buying right now is also okay but not optimal.
Some people do not buy bitcoin for investment but just to spend online only most especially in their gambling hobbies, I would say you are doing a great job since you are buying bitcoin and treated it for your investment, for sure you will earn profit in the future.
