This will more than likely take several years to play out (could be wrong) but the risk to reward here is getting ripe because we're well below the mean. I have a buy order at 6k. I wouldn't be surprised if it went lower but it's more risky to not buy at this level than it is to buy for the long term. We're sitting at a .67 on the @TIPMayerMultple so if it goes lower... I would get ready to dump your fiat into this with a dump truck. Given I'm not selling until the next bubble, I don't mind holding if it goes into the $4-5k range.
Not investment advice. Don't invest money you can't afford to lose.
