The most important 2 problems that Bitcoin can solve are:

Printing money without a end PROBLEM (limited supply)

Banks "printing" digital money PROBLEM, every time when you deposit money with your bank that bank can lend 90% of the sum to someone else, because it's must have only 10% reserve (can't do that with bitcoin because of ownership)

The solution to these 2 problems will give us financial freedom. Something that we did not even hoped for  before bitcoin.
