Can I use my Thai address on the DTV visa application if I already live in Thailand?

Hey. Got a few questions about the DTV Visa I'd love to get some help with. I'm applying in Taipei.

1. If you already live in Thailand, can you write your Thai address as your permanent address on the DTV application form?

2. About the bank balance showing 500K+ THB, does it have to be from the day of application or can it be from 1 or 2 days prior to application?

3. Should the passport copies be in color or black and white? I once had an immigration officer not accepting my application because the copies were in color.

Thank you.
