Bull markets don't always go up!
If this is your first bull cycle, we understand your fear.
But if you've been through these cycles before, you should remember that in the past, prices corrected even more sharply than they are now (vertical lines in the yellow rectangle) before reaching new highs.
As you can see, the corrections in the current cycle (white lines) are actually the smallest of all four.
History repeats itself:
Price increase -> profit-taking -> fear -> capitulation -> accumulation -> price increase
The key is patience and a plan. Don't give in to emotions!
