Good afternoon, which city are you talking about?

Good afternoon, everyone. Who do you think I can learn about cryptocurrencies from? I can't follow a lot of people or dedicate myself 100% to it.
But I need to learn in order to know how to invest.
I'm an entrepreneur and my work takes up a lot of my time, so I read a lot about it.
The more objective and practical the better. I would like to follow 2 or 3 people at most to follow their advice. Who would be the people you recommend?
Thank you!
