There are palenty of bitcoin debit cardfs in the market righht now, and they are fiarly cheap, but the problem with withrawing from them through ATMs, is they take a ton of fees for it, since they need to exchange bitcoin to your local currency, as for ethereum you can exchange it to bitcoin then withdraw or deposit them to the cards that i mentioned, personally i would not use debit cards to get my bitcoin in fiat, instead what i would recommend is that you go on localbitcoin and find someone in your country that is offering to buy bitcoin and pays cahs, that way you won't lose any fees and you will be avoiding any complications since bitcoin is not yet leagalized in your country.
