I’m not sure I understand what you mean. Are you only talking about deposits? Transferring money involves more than just that. As I mentioned, the transfer limit doesn’t apply to all users, it specifically refers to online banking. There are other ways to deposit money into the account, though they may require a bit more effort and contacting the bank directly.
I also don’t understand what you mean by “how many transfers of 50k are needed to reach 800k?” Where are you transferring the money from - abroad to your bank account in Thailand? As far as I know, such deposits can still be made without these restrictions.
