First of all, you should definitely add a Letter of Guarantee to your service.
- I liked how you use the number of confirmations instead of hours to let the user delay their mixing. But I would prefer if you let the user decide for himself instead of randomizing how many confirmations is needed. I tried creating a new session multiple times to get something like 6-10 confirmations but never got a delay lower than 14 confirmations.
- You should add a calculator to show how much the user will get after fees to the amount he sends. E.g: if you send 0.00153022
BTC, you will receive 0.00143492 after the 1%+0.00008
BTC fee.
A small issue: When I was mixing the coins, the "Total transaction fee" showed was "8.0E-5 BTC";
Right now, I'm waiting for the mix to complete (I choose to delay it). I'll edit the review with more details when I get my coins.I received my coins after the 14 confirmations and everything went well.
Also, just a quick fix to the previous user:
Fees: your fees are so cheap compared to all the mixers in the market (not only Bitblender which varies between 1 to percent) so how would you confirm that you keep this commision stable whatever the amount to mix or the growth of your compagny?
That's not true. At least 5 other mixers have a lower fee than the 1% he uses. And one mixer doesn't have any fees at all (it's a pay-what-you-want strategy), you choose if you want to donate them a small fee or not.
