I heard a theory of 10 000 hours, so as for me I spend in crypto like 6000 hours, so after a year I will become professional. But you know, it does matter what you do as well. I am not tech guy, I just full time trader, bounty hunter and investor in ICOs, also I have my own crypto course, so something like that
It takes a long time to become a professional, sometimes being professional is not easy and requires a lot of process and knowledge.
trading investment or other things requires experience and knowledge so you can move well and easily.
