Mixbtc.io was created for the bitcoin mixer community with three things in mind, trust, speed, and security. We understand that using a bitcoin mixer for the first time can be uncomfortable so we recommend splitting larger transactions into multiple ones until you’re comfortable with the process. The time that a mix takes to complete is usually down to the network fee that is selected, choose a high network fee to get your transaction confirmed sooner and the mix initiated quicker.
