Sell your kidneys if you have to, you can buy new ones next year when btc is 100k 
Hahaha that is a desperate move just to buy some bitcoins. 
But for someone that is willing to do that for how long is he going to wait before it reaches $100k.I don't think that next year 2017/2018 is going to be enough just to make the bitcoin reach and make itself into a 6 digit value coin.
But I won't do it anyway better to sell some unused goods that I don't need anymore and I would sell some of my coins but still keep on holding.
I think the price of the bitcoin will not be 5 digits. It will be around $1500 to $3000.
Many people are predicting that BTC can be 3000 by end of 2017 so anything is possible. I can also be worth 0. Nothing is impossible!
