What are the things that someone should have and someone should follow if they want to be successful in their crypto currency career?
Personally, I feel patience and resilience are key factors and analytical skills, keeping up with trends also need to be there but those all are just secondary cause the real deal is to avoid the capital loss that eat our whole capital in no time.
And I would call someone successful if they keep learning from their own mistakes.
Someone who keeps learning from his or her own mistakes is not more successful than those who keep learning from other people's mistakes.
This is to say that, one does not have to wait until he or she does any mistake before he or she can learn, such mistakes can be avoided by simply putting eyes and mind down to learn from other people's mistakes, this can be achieved through reading books and good online posts, watching educative videos and well as listening to really good news and information that is in relation with ones line of interest.
And it's also very important to have a good mentor as well, someone who have gone through alot in an industry of your interest and have succeeded, follow such a person and learn from him or her, there are mistakes he or she has made, which he or she will help you not to make same mistakes, which can help you succeed faster than relying on your own self and learning from your own mistakes.
