The Bitalo team has put some real effort in finishing a nice academy website that explains Bitcoin in all aspects, including background informatoin about the banking system and monetary system. Bitalo Academy not only wants to provide information on how Bitcoin works, but would like to explain to you why Bitcoin matters! Here you can get an integrated view about this complex topic. You will find thoroughly researched information about more general topics, like what money is, up to detailed technical explanations. Enjoy!
And yes, it is completely free of charge.
