Golden rule on financial investment can be an individual decision on what and how to implement such to suit their purpose, but one of it is what you have mentioned, i will like to add to that as well, ensure your investment is on what you're very sure about, don't invest on ordinary thing you just heard and know nothing about, carry your research before making an investment and be fully satisfied with all informations about the investment gotten from different sources, as for me, am not the type that like referral of a thing, I can't vouch on recommending you about something but i may advise you about it, the decision is left to your choice, what works for A might not really work out for B as expected.
I agree with this a lot. You have to arrange your own decisions based on what you can do personally and what type of person you are. You gotta understand that the point of the whole crypto trading learning experience is that every person is different from each other and their goals are different as well.
While one person could want one thing, the other may want something else. This is why I believe that we should not be really shocked at the fact that some people will learn it another way, while you learn it totally differently. Because your personalities and goals are very much different and that requires very different methods of trading as well.
