is it worth doing this when it is growing, or do you need to wait for a small pullback? There is a small dynamic, but I do not understand how to do next.
Investing requires planning and goals, not investing by feeling. You should clearly define when to buy and when to sell, and the profit you want to make...No one can know where the bottom is, the top is the top until it has happened, so it is important to have a specific goal and not be too greedy. Excessive greed will only cost us more than profit.
For example, the plan is that I will accumulate bitcoins until bitcoin hits $60k, then I will stop buying and will just sell all my bitcoins when it hits $150k.
