Real money:

yes youre probably correct and I agree with you. thats the main reason why cash is more likely use by people , but what i like bitcoin than cash is that we can earn it anonymously and here in my country, bitcoin is more higher in value than our currency. thats the sad thing about our currency, but all in all i like it both and use it both.
