This is the classic question that everyone asking about it. Then you do not get the job is that simple the same happens in the real world all the time. I guess you have to learn the basic knowledge of btc first. If you apply for a job and you do not fulfill the requirements then you will not get the job which is why people need to concentrate in getting the most skills they can before applying to any job. Before making any classic question like this. Not only in crypto but in any other space or the chances to get hired get lower. Just type on google, about "what is btc" ... "how to collect btc" ... and so on. I hope you find your answer and a way.
