How much tax will I get back if I made $10,000?

Excuse me, as a cryptocurrency and finance professional, I'm curious to understand the tax implications of a hypothetical scenario. Assuming I've earned $10,000 through various financial transactions, including cryptocurrency trades, what kind of tax refund could I potentially expect? I'm aware that taxes vary based on multiple factors such as personal income, deductions, and applicable tax brackets, but a general estimate would be greatly appreciated. Could you provide me with a rough estimate of the tax refund I might receive in this scenario?
