Do I need to move THB500,000 into a regular bank account for the DTV visa application in Thailand?

I had mine in a term deposit which showed it reoccurring after expiration every 6 months, greater bank account, i sent the statement for that and my regular account which only had approx a grand in it at the time but showed me transferring in regularly and using it for every day spending, i then attached a cover letter explaining i can withdraw the term deposit if needed and why i attached the latter statement. All approved no worries, i applied in Hanoi

Vast majority of embassies require the 500k in a regular bank account, You would need to contact the embassy you apply from if they approve of your retirement account being used
