Cash recycling is the next gen of all ATMs.

When the dust on the Bitcoin ATM industry settles, it will be industrial grade ATMs with barcode scanners and high capacity cash recycling that will prevail. IMO purpose built bitcoin ATMs will fall out of favor. The winners will be writing software that operates on standard ATM industry devices. The companies who manufacture them (and have been for years) will offer better support, warranties, and higher quality products as they are able to manufacture at scale.
