OHHHHHH thats right, you're not a normal person who believes in Bitcoin. You're trying to play the system and make a quick buck. So you *have* to have your coins sitting on the exchange, or you'll miss out on the dips!
If it wasn't for people selling and buying, how would the price get set?
The vast majority of people on these forums seem to think that Bitcoin can achieve "world domination" and go "to the moon" by being locked up in cold storage. They believe Bitcoin will somehow magically undermine the entire banking system of the world -- by sitting in fireproof safes in the form of paperwallets and encrypted thumbdrives that've never been online.
No wonder less than 0.1 % of the world's population have even heard of Bitcoin. The geeks are hellbent on making it stay that way, hence all the hatred spewed on everyone doing trading or using BTC as a means of exchange.
