Thought I'd share this from 5Dimes.
Greetings Daniel.
Thank you for contacting us.
If you use BTC to deposit you do not need to send any ID prior make the deposit and do not have to provide it to make a payout either. However please take into consideration the following statement: "Management reserves the right to request for identity and/or address verification or any other identity proof of an account holder at any given time without prior notice. Failing to provide valid and legitimate documents could lead to account closure and the forfeiture of any/all winnings and bonuses."
