There are different ways we can learn about Bitcoin and trading if we actually want to learn. It is either we learn from a physical teacher or online. It can be quite difficult and expensive leaning from a physical teacher because that can be some how expensive depending on where we want to get the skill.
When people is talking about spending money or paying someone to teach them Bitcoin always sounds ridiculous because learning about Bitcoin is a thing that shouldn't cost a dime from somebody, however is not even everything somebody will depend on people to teach them especially Bitcoin because everything is well explain online both the processes, so why pay someone to teach you when you don't have a limited access to internet, though I'm not of the impression that having someone to tutor you is bad but if it involves the person to pay an amount to have the Bitcoin investment knowledge then I don't support it because is not a difficult something and besides there are people who can teach you without expecting anything in return.
