sure. But depends on where you want to do for the day. I would go to the food carts and pay 65 to max 80. But if you go into any restaurant and eat Western food 300. Lol. It was just a rough estimate of expenses I put together for some friends that wanted to travel to Thailand.
Lol. Love this question. Over and over. Here is my pre covid budget from July 2019 when I was in between bkk and Pattaya. If you don't drink or date, you can save a lot.
To be completely honest with you man. Thailand is going to eat up that money you have and you'll have nothing left. That's not a significant enough investment to have any political power in Thailand. And any business power you attain along the way will be eaten up in thievery and bribes.
