Not bashing anyone, but this is worse than gambling, because families lose out when you cash in, not a casino. Every extra piece of pie is on that came off someone elses plate.
Families?
The average bitcoin user is a 20-something upper-middle class white libertarian male with money to lose. There are also these wealthy Chinese guys who pumped money into the market in the fall, and the venture capital firms and investment trusts. I don't think there is anyone here using bitcoin to try to feed their family. Everyone here is in the same game - to try to get as much money as possible, and came into it with the knowledge that their entire capital is at risk at all times. Almost nobody 'invests' in bitcoin just to help the technology - to do that they USE bitcoin, write code, or create services for it.
Your thinking is actually reflecting that of a ponzi scheme. "If you remove money, we lose". If bitcoin price was actually supported by its underlying economy, then people 'removing money' shouldn't be a problem.
You don't avoid selling shares, thereby depriving your family, so that someone else enjoys an artificially high price, that can't be realised until they sell anyway...
