However, I really don't think BTC is going to go much below 5000 USD. After all, Bitcoin core just patched up a major bug that was present for almost 2 years, and the market responded like it was just noise.

I'm fairly optimistic we are unlikely to drop below 5000 as well. However, I don't think the market reaction to the recent bug is any indicator. After all, both problem and solution became common knowledge in the same instant.
