It's really impossible, if not, hard to predict the exact direction of Bitcoin's price in the future, but if you look at the charts and zoom out, you will see that historically there was always an upward trend in the long run. Of course, there have been ups and downs along the way, and past performance doesn't guarantee the future. So, whether it reaches $50,000 or not in few years, that is hard to say, but it will eventually happen. If you're unsure about selling your Bitcoin now, consider making some financial goals and set your own risk tolerance. Maybe you could sell a portion of your holdings to cash in some profits while holding the rest for more profit. This way when the price goes up, or crashes, you won't be losing much. Just remember, as long as you haven't sold, you haven't lost anything.
