others have posted that transfers to Kasikorn or Krungsri are completed in seconds something Bangkok Bank used to do. Weekends are now impossible to receive funds.
The DTV is more than just a tourist visa due to its target audience being largely digital nomads and by allowing them to stay up to 180 days per entry. Someone staying here that long could be spending more and travelling to more places than a 30-day tourist. In this scenario a Thai bank account would be a welcome and useful thing to have. I would argue that a DTV holder could potentially stay in Thailand for most of a year which is the length of time that a retirement visa is valid for. The DTV holder is likely a digital nomad still earning a (good) salary compared to a retiree living off their savings.
Anonymous participant 953 I'm not going back to paying for the mototaxi or car with cash then having the possibility of carrying loose change around for the rest of the day.
