But if there be an ATM would it not make it Fiat again and would it still maintain the digital currency value?
Well, the purpose of ATH is to cash in to buy bitcoin and cash out to sell bitcoin, and cash out are more in demand as the adoption of crypto is still very small, we can't spend our Bitcoin for our basic needs since only few of businesses are accepting Bitcoin and massive adoption would only happen if there's a full regulation to the market which might take time.
