I agree with you, a business that has a high risk usually also gives hope of high profits, but with a note we must be a hard worker who never gives up and wants to learn. because with a difficult job like in Bitcoin this must be really accompanied by high knowledge too.
There is always a risk in every business you never become successful if you do not pass the risk. You need more knowledge to help you to learn, joining in bitcoin is not easy work you need more effort and time and most of all you must be knowledgeable before you become successful.
