I believe that the BTC will increase to $ 20k next year.
Well, I think you are not the first one to do such kind of all out action for Bitcoin. Here is another guy who think that Bitcoin will greatly increase in price in the future selling all his stuff. https://www.businessinsider.com/man-in-the-netherlands-sold-everything-for-bitcoin-2017-10.
