Bitcoin was created in reaction to the 2008 financial crisis and I think it has a bright future because the issues that caused the crisis have not been fully solved. Many people now realize that 'money' supply and interest rates can and will be manipulated by the government as needed and that the only real value is in assets, be it shares, gold or real estate. Those assets however are difficult to use as currency, so there is a need for a liquid store of value that is shielded from government interference but easy to use and move around. Cryptocurrencies will fill that role.
