A few friends of mine have asked me to explain bitcoin to them. I did my best, but I’m not the best at explaining things. They want to buy some bitcoins, but I’m not comfortable with giving such advice when it comes to someone investing. They asked if there are any resources or a book that would explain all the details of bitcoin. I told them to read the whitepaper but I also said I’d get back to them for more. Do you all have any recommendations? They have a good understanding of things outside of bitcoin because they are PhD students in Economics.
