If bitcoin has been banned in your country, then you don't need a bitcoin ATM. Why? because there is definitely no bitcoin ATM there.
But you can still convert it into the currency that you need through an exchanger, and it's very easy.
The same problem I face in my country. We don’t have any ATM cards and machines, but still there is a huge number of people who have invested in bitcoin and working in bounty and signature campaign and making money.
If I need money I will convert bitcoin into dollars and then in my local currency. So easy, so simple. No hurdles. Just concentrate to increase your volume of bitcoin wallet.
Actually the problem of some countries banned / illegal bitcoins in their area is not a big problem, there are currently some bitcoins wallet providers that provide Debit Bitcoins, which can be used in all Visa-based ATM's, even with a higher charge for each transaction
Indeed not all countries have ATM bitcoins in their region, so some bitcoins holders currently still rely on some exchanges to sell bitcoins to cash.
