Actually in this situation I think it is optional. We do need to learn about what bitcoin is and how to invest in bitcoin but we don't need to learn too much about investment theory if we really want to start because in the end this kind of theory will only make you struggle in learning but not dare to try.
In terms of investment, you can actually experiment while learning, because there really isn't much that needs to be theorized about investment as long as someone already knows which assets are the best and why those assets are the best. So it is necessary to introduce yourself at an early stage while reading several theories that can help you invest in Bitcoin.
I do not deny that learning is something very important but you should also try to directly practice what you learn because after all we can also still learn by doing so that the theory we learn is directly in the form of action in practice so that you know that what you learn is true or not.
That's what I meant above so studying theory doesn't need to take too long because in the end it also requires direct practice of what we have read previously. So learning while practicing is quite a good and complete thing to reap maximum results in a job and the most important thing is not to quickly give up on what we have done in a certain time after taking the time to study it and practice it on ourselves. Stick to good paths and methods such as DCA if you are also starting to like Buy the Dip, and Hodl.
