I will admit this was incredibly too long to be read yet it was very informative and can be useful most specially for the part of the newbies who were just starting up their journey toward Bitcoin engagement which involves investment as well as trading. Despite of being too long, the basic concepts are the only essential things that can be gathered in here that most of us do already know and it seems there is nothing new to be learned other that the OP have shared his experience on Bitcoin. Overall, it was good, the informations are well stated but those can be explained in a short manner.
Lessons learned from successful investors:
First: If you do not have even a small amount of anxiety over your investments, this means that you are not risking enough. You have to have enough money invested in order for you to have real interest. You will make the right decision when you participate in your investments with all your feelings, and then you will be able to monitor this investment and give it greater care.
Second: Get the profit as quickly as possible "Overcome greed"
Third: Beware of anyone who predicts the future, as all financial consequences are tolerable.
I beg to disagree on the key points you have learned on your Bitcoin investment journey but I do gradually respect it since it was your own learnings gained from your own experiences. (1) Doing investments with Bitcoin is already taking risks for you are putting your money at stake. No matter how small or big your investment is, there is still risks associated on it. Better start small rather than putting at high stake for many people are failing into their Bitcoin experience that putting up high amounts will ensure them to gain higher profits. Giving your all in an investment will literally give you anxiety so better start up small rather than fall too high. (2) You will be missing out better opportunities once you pull out easily just to gain easy come and easy go profits. You cannot be profitable as always on that strategy but since it is your own experience then it's fine. (3) No one must really believe on predictions for we are relying on facts from news, price charts, believing on such is like putting up your journey into a fortune teller.
