I am really interested in this question. And you might be surprised, but I came here not only for money, but on the first place I put the feeling that I can do something important. Cryptocurrency world is not a teaching, medicine or life guard area, but i am a strong believer that every person should do something important for him, his family and friends and for other people as well. So I am thinking of becoming some kind of cryptocurrency consultant or something like that. But I understand that in order to achieve this goal I need to have a perfect portfolio and to become a highly qualified professional myself. I am ready to hard work for years, but i want to know how much time will I need? One year is not enough but what about three or four years? Will it be enough? What do you think? Thank you very much and good luck with your business.
"Cryptocurrency consultant" sounds vague.
You mentioned portfolios, I assume you mean a trading consultant, in which case you can't start a youtube channel early enough.
If you consistently show people how to trade well, you'll have a huge following and finding clients will be easy.
