Even if i will get the opportunity to have bitcoin ATM business i'd rather not because there are post here of a bitcoin atm owner that has been establish at mall and other areas to where he admitted that he put up an atm bitcoin to the authority where had told him that he is doing it illegal. He will probably gone to prison for that or it could be settle within the authority level. I hope that guy can still recover the losses that had been made after the arrest. So, if you are planning to have a bitcoin then be sure to register it to proper authority so one will not have problems when it comes to legal. It may cost you for the processing but at least you will be safe from getting arrested of illegal operating on bitcoin atm.
