Never say never - I think it's definitely a possibility, but there are a few factors to think about when speculating BTC prices. Like all currencies virtual or otherwise, it's still subject to the market cycle. Even with BTC's current bullish run, from now till 2020 we're going to see quite a lot of highs and lows throughout and I personally think that with the time period and market cycle - it'll take sharp growths in order for the price to grow exponentially to 100k. BTC is still pretty volatile and while we are seeing great growth these few weeks, it only takes a whale to do a single big BTC transaction for the price to dip/crash, like it happened on May 17. It'll take something drastic for the price to rise that high I think which also includes other factors like worsening global political tensions, a huge global recession etc.
