Of course it can change the economy system. There are many unemployed people who has diplomas and are sitting in their home doing nothing but waiting for their government to provide them with jobs. Bitcoin is a golden opportunity to help those people who are in need. Therefore, if the government allows them to use bitcoin; mining, etc... then half of people's financial problems will be solved and the economy will rise.
Bitcoin can surely change economy of a country and all the economics rules will still use in the digital market. The guiding principals are not going to be changed and will not change as these are universally accepted rules and are the major lines of every other investment or business. Bitcoin follow the supply and demand rule and also follow the graphing analysis on economical system.
