This was actually posted on 4chan during the bear market sometime last year. So far the prediction was fairly reliable. Now its possible for Oct 2019 to hit $16K, there were days when we had +20% days. So it seems doable however the other predictions are far fetched.

I don't think its possible to go from $29K to $56K in 6 months or from $56K to $87K in as little as 4 months. People need to realize that for price to hit those levels there needs to be massive adoption. Someone needs to buy your BTC you are selling and I don't think too many people would want to pay close to $100K for a single bitcoin, especially in about a year or so since in a few months the year will be over.
