Bitcoin Forum

I've been a software engineer / web developer for some time now and most recently got into Bitcoins. Invested a little cash, and bought a Radeon 7970 for mining !

I noticed there were only a few sites which offered Bitcoin "laundering" so I decide to make one myself with a very low commission rate (.9%) .

Wallet file is not stored on web server and transactions are all handled manually.

More tools and information resources will be added but I'd love to give the bitcointalk.org community a first look at the site before I remove the robots.txt restriction and allow indexing.

Please let me know what you think and feel free to test the "Coin Scrambler" out!

Thanks,

nice

Didn't try it yet but looks very good.

One thing though, you seem to miscalculate the commission with a factor 100 :)

If I want to transfer 1 BTC, the commission rate of 0.009% should be 0.00009 BTC, so I should transfer 1.00009 in total. However, instead it requests 1.009 BTC to be sent.

Perhaps you confused a factor or fraction of 0.009 with 0.9% :

9% of 100 BTC is 9 BTC
9% of 10 BTC is 0.9 BTC
9% of 1 BTC is 0.09 BTC
0.9% of 1 BTC is 0.009 BTC
0.09% of 1 BTC is 0.0009 BTC
0.009% of 1 BTC is 0.00009 BTC

Looks nice  ;)

I don't get it...  ??? = newbie

Thanks for the heads up, I meant .9% and was displaying the # used
for calculating.

- Application has now been updated to give a unique "send to" address for every request.
- Minimum amount to "scramble" is now 1 BTC.
- Commission percentage display has now been fixed.

So under what circumstances would a coin scrambling service be useful?

Toby.

P.S. Hi! to the other Toby. :)

A coin scrambling service is useful to dilute or make the trail of transactions more difficult to trace. Increased anonymity.

If you really handle each transaction manually, you will have your hands full.

how hard would it be to automate the scrambling?

Why?

For anonimity purposes (making it harder to trace coins), I'd say it's better if all scrambling is done through one common address.

Automating the scrambling would be possible, but I'd rather handle everything manually due to security. An SSL Certificate has been added to the site as well and will be active within 48 hours.

Thanks for making this.

You are very welcome. SSL encryption is now active on the site.

I'd really like to stress this point again:

And also, to further increase anonymity, you might want to consider restricting the amount of coins to be scrambled to powers of 2.

If I send 173.54 BTC to your address, which is probably quite a "unique" amount, and then you send (1-0.009) times that to another address, someone might still kinda recognize it.
If I send 128 BTC to your address, along with lots of other people, you would send just as many payments of 126.848 out to other addresses, and nobody can tell one address from another anymore (thus not distinguishing anyone in particular).

Interesting idea. Financial privacy is important and services like these are a great idea.

Glad it will be useful. Opened site up to search engines today.

If I scramble some coins through your website now, and I do it again next month (with different 'dirty' and 'clean' addresses), can I be sure there is no chance I am receiving my previously 'dirty' coins from last time?

You have "dirty" coins  ???   ;D

Yeah man, got shit smeared all over them :-[

So I'd like to change those for some fresh ones. Wouldn't mind if somebody else's shit is on them though, I'm not too picky :)

Just send me some of your dirty ones and I send you mine (same amount, not so dirty)  8)

This is a great idea, perhaps to enhance the ease of use you could have a series of set amounts you could send like 1, 15, 75 and 200 so all the incoming would be just those amounts and outgoing amounts would be those, minus 0.9%

This is brilliant and probably the start of a future market.

Of course, I receive 'dirty' coins in a different wallet, which is never used for outgoing transactions.

On another note, just processed 1st real scramble request. If whoever took a leap of faith to see if I'm trustworthy wouldn't minding vouching for my service, it'd be greatly appreciated.

That would be me :)

Kudos sir, and thanks for your fast service. I had my fresh new shiny bitcoins on the new address sooner than I expected.

Not planning to do anything illegal with it or something, I just want to make a small payment that is impossible to trace back to me.

Thank you, and you're welcome.

I have coins to scramble. There are good sites like instawallet, easywallet. What is your selling edge (advantage)?

How do you use instawallet or easywallet to turn your current 'dirty' coins into new ones that can't be traced back to your current address?

I create 2 instawallets, send the coins from 1. to 2. then to my private wallet.

Exactly what advantage do you gain with this?

Once you want to spend the coins from your private wallet, people can still see they originate from instawallet 2, back to instawallet 1, back to whatever they originally came from. Coins still dirty.

The idea is to somehow swap the coins you currently have on address A, for other coins on address B that cannot be traced back to A. No chain of transactions should exist between A and B.

Afaik in instawallet you cannot trace them back. Try it!

Hmm, doesn't seem to offer any real protection.

From bitcoin.it wiki (https://en.bitcoin.it/wiki/Instawallet):
Seems kinda bollocks to me, as an email address is not required to use Bitcoin AT ALL. Maybe for some 3rd party wallet websites might require users to register an account with them, but this is completely independent of Bitcoin itself.

Also, when you pay from your local (or any) wallet to instawallet 1, instawallet 2, to some other address X, anyone can simply trace back the coins in X coming from 2, from 1, and back to original local wallet. This is not a shortcoming of instawallet, but just a corollary of the way Bitcoin works. So no, instawallet doesn't help in any way here.

Thats not correct! The coins in x dont come from 2. > dont come from 1. They are mixed on the way. I made a test transaction to check this. You could also ask the guys from instawallet here in the forum.

I tried it: I sent some bitcoins from my 'dirty' address X to instawallet A, from A to instawallet B, and from B to my 'clean' address Y.

Indeed, the transfer to B did not come from A (I guess the site uses some kind of intermediate coin caching system). But strangely enough, when I sent some coins from B to Y, they came from A!

So, the coins in Y can be traced back to A, back to X, and thus they're still dirty...

With bitcoincache.com I send from an account that BTCs are obtained either via mining, dividends from GLBSE, or purchased w/ cash.

Great site.  Will be using it soon. But I still don't understand how you handle the requests personally by hand.

As of now the requests are limited and I have a system established !
