Actually - no. If bitcoin was a lot less volatile than it is right now i believe that it will achieve even greater popularity. I think that you're assuming that even in the short term bitcoin is able to achieve fabulous results all the time. That's not true. If you buy in at the all time high and sell when the crash happens then it's obviously not a good short term investment to make.
OP, with the benefit of hindsight the price of bitcoin itself have answered your question - the price has went up some $1500 between the original post and right now. Holding is a good strategy if you're not planning on trading, and you just want to have something locked away for your investment. Holding might not be for you if you're worried about short term fluctuations.
