Which ATM's I guess you mean shitcoin.club brand because everyone else is already under KYC/AML stuff
Initially I did not mention ATM brands because I did not want to advertise them, but yes shitcoins.club are the ones that that have a brand name, don't require KYC, phone number or email. Also I think that their buy/sell spread is the one of the lowest among the crypto ATMs that I checked. Right now if you buy/sell DASH, the spread is about 10%, which means that in one direction it will cost you about 5%, which is a very good deal, if you want no KYC for a low price
There is at least one other vendor in my vicinity which has crypto ATMs under the name "Bitcoin ATM" (I am not sure what is the real name under which they are registered). They say that they don't require KYC, phone or email either. Again you can get cash, and their max. limit is slightly higher than the one imposed by shitcoins.club, again depending on the country's legal limits. My guess is that if you look around there might be other vendors too.
There's also the annoyance of ATM's not having funds when you are withdrawing. shitcoin.club shows current funds per ATM on some spots but I doubt the websites I doubt are updated in real time.
shitcoins.club seems to be updated in realtime or at least daily. When they run out of funds they are refilled within 24 hours, but I guess it probably varies depending on the ATM location.
The thing is, even in the so called free of KYC ATMs like shitcoin.club, you are still trusting that they don't have undisclosed deals with the government. Realize the fact that these ATM's record you, and there are recordings nearby as well, you can get profiled.
I agree that there is the risk that they might be cooperating with the government(s) and/or profiling you, but then again, with the crypto ATMs you know that they might be doing that, while with the banks you can be sure that they are doing that because they are required by the law to do that. Those using bank services are completely transparent to the government and being profiled and analyzed in realtime. Additionally they record and store that information for at least 10 years back in time.
Cash by mail is a moot point and varies on the jurisdiction. It is either illegal or legal if you declare it or if you don't declare it then it might not arrive or even worse arrive but be reported to the government at the same time.
One other option is just looking on the social networks for local groups that are interested in crypto. I know that shitcoins.club have a facebook group and most likely they are not the only one. So my guess is that one could use these online groups to establish connections with other crypto enthusiasts and then meet them in person to trade crypto for cash. Again again, one does not have to use his real when registering in these online groups...
Soon it will just be impossible
I agree that soon the time will come when all crypto ATMs will be forced by law to require detailed KYC for each transaction. So it is important by that time to have established horizontal connections with other reliable people that you can meet in person and trade crypto for cash.
At the end of the day we are going to need to really push the currency side of BTC because trading for cash will just be mission impossible.
It is nice to use crypto as real currency but we must be realistic. The currency side of the crypto is the most dangerous one to the governments and they will do anything they can to prevent that from happening. If the government cannot control the money that circulates on its territory, then it essentially cannot control anything going on on its territory. So I think that crypto will be legal tender only in relatively poor countries with unstable financial systems. And even then they will only allow transparent currencies like BTC which have very little privacy. For example I don't think that they will allow Monero, which is arguably the real crypto currency unlike the ones with transparent blockchains.
So we have to be realistic with our expectations and look for KYC-less ways to convert crypto for cash. The real trouble will be when they introduce CBDCs and phase out cash. Then we will be living in a totalitarian dystopian society where it will be possible for the government to monitor anyone in almost reatime and "cancel" anyone just with a few clicks on the keyboard. Until then I think meeting a reliable acquaintance in person and trading crypto for cash is the method that works best. Then again your mileage may vary and cash by mail or other method might suit you better.
