It really depends on your area on what country are you in to because here in our country we have an online wallet here in our mobile phones and with just a tap on that yhing we can convert our bitcoins into a cash by withdrawing it into a bank and even without a credit card we can get in into an atm machine wuth a code so if you country do.mot support that thing then better ask the google on how it is done into your country and if it is legit
