do you want to have a stress-free Visa renewal?  keep the money in the account and during the 12 months of your first visa, deposit ฿65,000 into your thai bank account  moving yourself over to the monthly deposits category.
It was easy to deposit the 800,000b in a Thai bank which eliminated The need to buy private medical insurance which gets canceled the moment you start using it, what a waste of money! Once the money is deposited in the bank then you can start adding $65,000 baht or about $2,000 USD a month into the same account. When you've put in 12 deposits, in the second year you can qualify for the income method. Overall much cheaper!
You do realize the intention is for you to participate in the economy. that means spending thousands of dollars. if it's your intention to spend nothing and say that you are constantly taking cooking classes, good luck! you'll just fly into the country one time and they'll go show us all your cooking classes and you'll say I am not taking any and then they'll say go back to your country! NOW, sounds like fun ☺️
