Since Bitcoin's insurrection it has been growing on an unprecedented logarithmic scale. According to this logarithmic scale, Bitcoin's realistic resistance should lie around 60k.
Seeing the growth of the past couple of weeks, another 50% increase in price should be reachable within two months or less.
After hitting 60k, there's much uncertainty where Bitcoin will go. Most likely we will see a correction somewhere in the near future. For now, enjoy the ride!
