You can bank on the knowledge and experience of a friend and take this opportunity now the price of bitcoin is low to invest, but you will also have to dedicate yourself to learning as much as you can as quickly as you can. I say you should invest and learn along the way because waiting to know enough first can make you miss the opportunity to invest now the prices are low. You can also lose interest if you are waiting to learn everything first, invest now, so you will be dedicated to learning more about where you have put your money.
