For me in this kind of market traders is made which because of the power of crypto currency that can change ppl life. Not born in my opinion 'cause since this crypto currency is not yet popular mostly are investor and advertising which trader doesn't exist on that time .
Even if you are not the chosen one, you can be a made trader by spending time in the field. In addition, you can become an expert in trading in just six months by giving time to the important aspects. So I think there is no difference between a trader born or made. What matters the most is the value that is generated as a result of the trading.
Practically, I believe these two types of traders are always existing in this space. Because, it will not be possible to have some extra perceptional knowledge for all the people but it is a knowledge by birth. This way, some people may born with extra sense on catching anything sharply and obviously anyone can turn into professional trader for sure by learning and practicing.
