in my country, bitcoin can not be used as a valid payment tool of any kind because the bitcoin digital currency can not be launched here, especially if bitcoin is used to pay for training course fees, it is highly unlikely that payment using bitcoins is acceptable. but by prohibition does not make the use of bitcoin can be prohibited here as long as it can be in accordance with existing legislation that is exchange currency bitcoin to local currency first. Maybe it's only in japanese country that I know many training places that can accept payment using bitcoin.
