This is actually a wise step to increase a mass adoption of Bitcoin, but however, base on what I heard from online and other forums, I was told that withdrawing fiat from a Bitcoin ATM machine is quite expensive, as the operators charges high transaction fees just because they have only few of them, but if this number could be added, I think this will bring more competitors into the market, and as a result, cause a decrease in the transaction charges
If you missed reading my previous post, the US has over 34 000 crypto ATMs, and if I'm not mistaken with the ones located in Canada it holds over 90% of the total number of such ATMs globally. Regardless of the number of such devices, one should not hope that the fees will drop significantly, because the costs of purchasing, maintaining, and installing such devices are not cheap.
Maybe someday in the future every ATM will have a crypto option and then the fees will be much lower than today, but until then we should not expect to buy or sell Bitcoin on such devices cheaper than on online exchanges.
