<prompt> Human: I have a few friends who are swept up in the bitcoin craze. It seems like a pyramid scheme to me, but the value is rising every day. Are you investing in bitcoin? Why or why not?I would have posted this to rbitcoin, but Im guessing it would have been removed immediately for non-fanatical conversation of the topic.  <response>: Its rising every day until it isnt. Youll buy it and itll rise. Youll hold it and itll fall. Youll buy it when it falls only for it to fall some more.Bitcoin is not an infinite money pool. Its speculation, and there will be huge winners and huge losers. You could be either.
