I am self employed and in fact since COVID did not work at all. So the LTR visa requirements are completely impossible for me to accomplish. The DTV is a nice new option, which I will pursue :D
The rumour/or unofficial news is that thee is a new via coming up. "Destination Thailand Visa" (or something like that). For that you would need 10k in a Thai bank account and get a 5 year multiple entry visa that grants you a stay of 180 days per entry. It was supposed to launch 1st of June, but it did not. Depending on how soon you want to come, that might be an option. If you do not have the 10k EUR, I guess you can ask your employer for a laon.
