Can I use multiple personal bank accounts to meet the 500,000 THB requirement for a Thai visa, or do I need to maintain it in one account?

I currently have two personal bank accounts where I usually keep around USD 5,000 in each. I also have a third personal investment account with approximately USD 200,000 in stocks.

In addition, I hold shares in two LLCs: 33% in one company and 50% in another. The bank accounts of both companies have maintained an average balance of around USD 100,000 over the past 12 months.

What I am not fully clear about is whether the requirement is strictly 500,000 THB in a single personal bank account, or if it is acceptable to demonstrate overall financial capacity by showing multiple personal accounts, investment holdings, and company accounts.

In other words, would it be necessary to transfer and keep 500,000 THB in one personal account for a certain period before applying, or could presenting diversified financial evidence (personal accounts, stocks, and company ownership) be sufficient?

Thank you in advance for your clarification.
