the LTR does not require investments but it requires 50,000 US dollars in insurance coverage, or 50k in the bank. It also requires you are receiving either 80k if working or 80k passive income. The amount of income can be reduced to 40k if you have a masters degree. In both cases it needs to be in a job not competition with Thai workers (digital/remote).
Also the company (if still working and not passive income( has to be public, above a certain size and generate a minimum revenue per year so small companies are almost a non starter
Also, there is no issue with taxes
