of course bitcoin can used for good thing,lets see some foundation that accept bitcoin,bitcoin not just used for money purpose,and i dont know why people always show bitcoin used for illegal acitivity than show bitcoin for good purpose 
Yeah I heard that some foundations are accepting bitcoin. To my sense bitcoin will be used only for good things. It grows up only because of its goodness. i think that bitcoin surely might be used for making good things not only bad and i hope that there will be a lot of companies that would use others bitcoins for good causes
