Can I join the line of testers? My addy for this: 1EHn8kLwjSShHQi6DBZzk4Fvc2ygV7Bw6i
After testing, I'd like to challenge anybody to find back the mixed coins. I'll send them to the first person who posts their new address (this offer lasts 1 week, I don't want to reserve coins forever).
Great idea about challenge! It will be very interesting =)
P.S. money sent trough mixer, soon will be with you =) and we are waiting for your test and feedback!
Some thoughts (I may be a bit harsh, sugar coating isn't helping you to improve things):
1. The FAQ says the deposit address is valid 24h. What happens if I deposit, and before it confirms the Bitcoin network gets congested, resulting in my transaction still being unconfirmed after 24 hours?
2. You say you don't store logs, and "All logs are deleting". If you don't store them, you can't delete them. If you do store logs, chances are they can be recovered after deletion. Which one is it?
3. To look more professional, start all sentences with a capital character. For example: "we provaide a digitally signed confirmation" should start with "We". There are more language thingies that can be improved (and this is coming from a non-native English speaker), you may consider asking someone to proofread everything.
4. Is the delay set at exact hours, or do you add some random minutes (0-60) to make it less likely to identify transactions?
I can answer this question for myself now: it's quite accurately 1 hour. I suggest to randomly add 0-3600 seconds.
5. Your Letter of Guarantee has a "random" Bitcoin address. Why don't you use a vanity address for this? I have a
giveaway for safe vanity addresses, but yours will be too long to create for free. An address starting with 1Bitsafe or 1BitSafe would be possible, starting with lower case 1bitsafe would take much more computing power.
6. Your Onion address looks random too, it would be better to search for an address that starts with your name.
I've tested some other things, like importing the Transaction ID into the Tor site, and that worked fine. The site is quite simple, so there really isn't much more to test

Now back to my challenge: I've deposited
this transaction, used the default Service fee (I'm not telling you how much exactly), set a delay anywhere from 0 to 23 hours (I'm not telling you my choice), and I lowered the fee
because fees are low.
The first person to post my receiving address (OP excluded
), receives the funds. This offer expires in a week.
Note: at the time I post this, my deposit is still unconfirmed and the return transaction hasn't been sent yet. It does say "BTC received. Awaiting 1 confirmation".
