Well put it this way...if you put $15K in bitcoin ira in 2015 - your portfolio would be worth $155K. If you did it in 2016, it would be worth $59K. Of course - you need a stomach of steel for some of those dips lol. That said, profits are nuts. just google bitcoin ira - I spoke with some one there and he was super knowledgable. The one downside (or upside depending on your financial situation) is that it requires a minimum investment of $15K.
