There are two mixing options:
-Mix your Bitcoins: you send what you have and get back clean coins, optional features are
multi wallet payout (up to 5) and time delay.
-Pay Anonymously: you choose the amount you need to pay to a service or someone, then send the
exact amount shown and the mixer will make the Bitcoin payment for you anonymously.
This obviously works both if you need to pay someone or if you need to get paid.
Sounds like they're the same idea in nature; someone puts coins in, and coins that aren't connected to him or her are sent to a chosen address. Is there any notable difference?
Also; why should we trust you? Other mixers that have been operating for a longer time are doing the job perfectly well.
