WebMixer recently did a total makeover of their site. I gotta say, the new design looks real slick - modern and easy on the eyes. Works nicely whether you're on a computer, phone or tablet too. I gave it a test run on a couple different browsers and devices and didn't run into any issues.
The interface walks you through mixing your Bitcoin quick and painless and within minutes I was able to complete the process and see the newly mixed coins in my wallet.
Security-wise, I'm impressed with what WebMixers offering. They give users a few different options to dial up the anonymity - "Basic Anonymity", "Precise Payment", and "Max Anonymity". Each has its own level of privacy protection, fees, wait times deposit limits etc - so you can pick what makes sense for your situation.
I chose the Basic Anonymity option for this test. The anonymity is lower than the other choices, but the fee (1-1.5% plus 0.00035 BTC) and mixing time (0-2 hours) are also the lowest.
After entering your address to receive the mixed coins and hitting Mix now, you go to a new page with the address to send your BTC for mixing and the choice to download a Letter of guarantee. Make sure you download this before sending over your BTC.
Then just send your bitcoins to that address and wait. To start the mixing, your incoming transaction needs 1 confirmation on the network.
Here are some of the things I like most about Webmixer:
The interface works nice and smooth
Tor mirror helps keep things private
Multiple mixing options
Secure and anonymous
Reliable and trustworthy (service has been in operation since 2020)
Some of the things I didn't like about the mixer:
It might not be so great if you just need to mix a tiny bit of bitcoin
The fee they charge has a fixed amount of 0.00035 BTC on top of the percentage, and it goes up to 0.0007 BTC (for precise payment and max anonymity modes)
Overall, mixing my Bitcoin with WebMixer was smooth as expected. It is a safe, secure, and anonymous service that is easy to use and provides great value for money. However, this is not an endorsement, WebMixer worked great for my purpose at the time, but you should always do your own research before using any crypto service!
