Topic: [ANN] bitcoin mixer bitsafe.pro - minimalistic design and lowest fee on market! (Read 1298 times)

This service isn't working anymore, which is weird since they just came back after more than 4 months offline to ask for $10 to do a review of a different mixer, and immediately left again. I guess they were just a bunch of scammers since the beginning, and since they didn't get a single victim, they just closed their website.

We are happy to inform , that we added no java version of mixer to onion link:

http://u44owaemhwuttvwv.onion

mixer automatically detect when java off and provide you no java version with maximum anonimity!

Now we working on improvements!

We are happy, that you guys weren't found the root wallet =) so now we have to add some improvements and increase bankroll , then we will start new testing challenge!

My offer expired yesterday. Nobody was able to find back my mixed coins, even after some hints. They were sent here!

This is my letter of guarantee (click to verify):

I just realized that I'm using total output, and not the value of a specific output. That's probably why, as the mixing transaction would likely have change.

I can't find it in there.

This is something that can be improved indeed. Fees don't necessarily have to be totally random, but transactions can be further obfuscated by copying fees rates from other transactions/services.

That sounds like me

Good, because I just realized I was using the wrong dataset.  
I was searching for outputs of 0.0018 to 0.00195BTC, but you deposited  0.00202082BTC, which would be ~0.002BTC after fees.

---

Edit:

I still can't find it, so I'll give up. This was the dataset that I used. It contains all the transactions greater than 0.00195BTC total output but less than 0.02028BTC, between the time LoyceV sent his transaction, and around 30 hours later. I noticed that bitsafe.pro used almost exact values in fee/kByte, so I searched for transactions with a total fee/kbyte of a value very close or equal to 2000, 4000, and 6000. (respectively a 0.00001BTC, 0.00002BTC, 0.00003BTC fee on the mixer site). Either my dataset is still flawed, or LoyceV picked a higher fee (but 1 sat/byte would have been able to confirm, so I doubt it), or bitsafe.pro used a fee that wasn't as close to those values. Looking forward to finding out which one it is!

All wrong
Maybe I should limit this to one try per person^*, if you just give me a list of possibilities for me to pick from, you don't know my address, which means the mixing worked.

I haven't spent the coins yet (because I may have to give them to someone here).

^*Update: I won't limit it, feel free to keep trying

Here's a few more guesses: (also, have you spent the coins yet?)

1DvHWbue1ZGPUZaiMpMHBVaevPK4pc2ce8 (spent)
1HXhaXJu4dHNxahm4PbYe77AFCU4ofCeUe (spent)
1M9QXAfxDjp3iHFNsMy44nfMrC8tCzipb9 (spent)

Also not mine
I'll post my Letter of Guarantee after a week, or when someone finds my address.

That's my address

My best guess is the address 1BSNnBo9dQvjWgu1NqhfYWdmRM2fv73oxy, with this being your mixing transaction. Only reasonable possibility I see.

No.

Did you sent them to a P2SH adress? I've found a trail but it seems that this one would a bit too obvious to actually be your receiving adress (+ the fact that the fees are actually a tad bit high on the transaction itself...).

Thank you guys for your feedbacks. NoJS version will be ready soon. Also we will work on other improvements.

To start, stop requiring JavaScript to be enabled. NoScript is bundled by default with Tor, and privacy/security conscious users generally disable it as it prevents malicious scripts from being run. A slider is nice, but perhaps add a dropdown/text field if you detect that JS is enabled. No mixer should require JS. I cannot change any of the default settings without JS, which is bad.

I wanted to use Tor for mixing, so I went with the default settings (0.00007 BTC fee, and no delay). I think every other tester used a delay, so I figured I would try no delay (plus, Tor users or users with NoScript would have to this anyway right now)

To no surprise, the auto updating page didn't work. I would remove the spinny circle thingy (no clue what it's called) if the user has JS disabled, as it is confusing, given that the page cannot update. To my surprise, even with a refresh, the page does not update with NoScript. It works on my normal browser (Firefox 61.0b5, no script blocking), but never loads on Tor Browser. (7.5.4 (based on Mozilla Firefox 52.8.0)) You should probably fix that, so that Tor users have a better experience. Enabling scripts seems to fix it though. This is due to you making POST requests via JS to index.php, and I think it would be better to just have it be displayed on the page (perhaps dynamic page generation), or use a PHP iframe or something.

A fee of 7k satoshis causes your mixer to pay a fee of exactly 14k satoshis/kByte. This seems to be consistent with my previous mixing transaction, where a 1k sat fee causes your mixer to pay 2k sat/kByte. Instead of


Something like this would be better:


Instant forwarding worked well, I got my BTC a few seconds after the first confirmation on the deposit transaction. I would suggest that you either go through all your text and fix it so that it's in better English, or hire someone to do so. Poor english looks unprofessional.

How long is it before deposit logs are deleted? My previous mix's info still has the data shown.

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".

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!

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).

Thank you DarkStar_ your feed are very useful for us. Maybe you have an idea how to explain more lucidly this moment in FAQ, we will be very happy.


P.S. money to your wallet already sent , check you wallet and we waiting for your test =)

Sure. 3NSvhvYYBMVh1bPyKWjPfyiF3RHAAgsgtw

I think you still need more clarification, as simply stating that it affects confirmation time doesn't really help. What exactly does the fee value represent? Obviously it can't be a fixed fee as you might send with more or less inputs.
