DTV is not intended for people to reside in Thailand. The future of the DTV is in jeopardy past its initial 5 years. The elite visa has been around for over 20 years
If you have the means, but not the annual income required for the LTR, the Elite visa works well. Still have to do the 90 day report, but do not have to worry about bank accounts, bank balances. And if you like to travel,every time you re-enter it automatically renews for a year at no cost. Most expats do not wish to or cannot spend the upfront money.
