Yep digital nomad is good , so you should easily be able to make the amount I've stated , after getting the Visa , and the variables of transport and accomodation .
So in that case there is no answer , other than the more the better so you can invest , and in case you want to leave .
So , I'd hold it as invested savings . Good luck ..
As long as the income matches the figures I mentioned which it should easily , it can be done .
You need an income , so savings must NOT be spent they must be producing income , easy rule of thumb MINIMUM ( can spend whatever you like in the top ) after transport and rental ( variables ) you need 10 k baht per week ..After rental / trans .
So if you are going to have a car , and decent accomodation that equates to 65 k baht min , on the assumption you will drive .
So the important figure 10 k min per week , plus us ..again minimum, if you cannot do that , DONT do it , simple , you are expected to live this way as a minimum.
