What are the steps and requirements for obtaining a Thai DTV based on crypto trading income?

Tips for obtaining a Thai DTV based on crypto/stock trading income?

I’m considering applying for the DTV based on supporting myself through crypto trading. I’ve done this for the past five years.

I deposited the required funds into my bank account in April. The account has a five-year history of irregular transfers from realized trading profits, although the balance was usually low because I withdrew only what I needed for living expenses.

I’m considering submitting:

* A cover letter explaining my trading activity and source of funds;

* Exchange/broker statements showing realized trades;

* Bank statements showing the corresponding transfers;

* Evidence that the required balance has been maintained since April;

* Tax or social-security documents, if relevant.

My country does not tax crypto payouts, so I do not have income-tax returns showing this income.

Has anyone successfully obtained a DTV using crypto or stock-trading profits as financial/source-of-funds evidence?

I’d especially appreciate information about:

* Which embassy/consulate you used;

* Whether exchange or broker statements were accepted;

* Whether a cover letter helped;

* What additional documents were requested;

* Processing times and the fastest legitimate application route.

Would a financial-support letter from a parent, together with evidence of their savings, strengthen the application—or would it complicate an application based on my own finances?

Thanks!
