Crypto currency is known to be a digital currency, a lot of us have suggested that there should be a crypto ATM to ease and hasten the use and general acceptability crypto. But if there be an ATM would it not make it Fiat again and would it still maintain the digital currency value?
The crypto currency ATM's (or better known as BTM, Bitcoin Teller Machine) is not for cashing out paper money or anything related to fiat, it is there so you could cash out your bitcoins into fiat which doesn't mean bitcoin becomes fiat in that sense, it is only exchanged but there is still a BTM company that is holding that Bitcoin in that case, or it could be used to buy bitcoin which is exactly what the adoption should be for.
So, long story short BTM is usually for people who can't reach to local exchanges or want to get their KYC known so they do it secretly using a BTM. It is also great if you are in a country where you don't have fiat, or you have extra fiat which in case you could get local fiat or you could get bitcoin in exchange of local fiat when travelling to other nations.
