Suppose I want to share my public key for donations, but the problem is everyone can see how many btc I have. Suppose I create a second account for donations but now people can see where all the btc goes from there and cunclude it's my address. How to share a public key and still hide my savings?

Donation wallet => exchange => your real wallet.

You can use a "mixer" or send the bitcoin to an exchange and after withdraw them (quickly) to another your bitcoin address.

Don't you pay fees when you send and take from exchange?

donation wallet => any crypto currency exchange (poloniex, bittrex, hitbtc, ... name it) => (trade) buy a stable altcoin with low transaction fees (dogecoin?) => transfer that altcoin to another exchange => (trade) that altcoin back to bitcoin => send it to your main wallet.

Yea, that's the only catch. But most exchanges aren't that expensive.

Why transfering back and forth to an altcoin?

This will incur much more 'fees' but it'd be virtually impossible to track.

Or you can use blockchain.info's Shared Send option which is almost free but less protected.

You need to decide how much you need to hide your main account and most probably the price/fee will go accordingly.

If you want to hide your coins sufficiently it's going to cost you a little bit. You can send them to any other website such as a dice site or exchange or mixer then send them back to a new address but this is the only real way you can do it.

Give every donor a different address to send to.

Then nobody will know how much you received. They'll only be able to see their own transaction to you.

You need Exchanger Wallet..

Any other method has a chance to get to this:
Your Public Address => Intermediate (Exchange?) address => Your "private" address
which means it's not the private anymore.

With my method, from outside anyone will see:
Your Public Address => Exchange address => money spent.
Some other exchange address (altcoin) => Address for same altcoin on different exchange (nobody will track / care about that)
Some address nobody cares about (your BTC address on 2nd exchange) => Your private address (again, nobody will track that).


If you are a drug dealer or such, I just saved your butt, so I'd expect a generous tip. My public address is in profile.

Easy. Mix your coins with different addresses and point it out to your main address. If you want to have an address for public donation, just generate a new one and mix your coins as well.

Plainly genius my friend. No one will care about an address from an exchange to another address. Traceable, but not that easy.

You have a lot of possibilities here , one of them is to generate different Bitcoin adresses for donation for each time someone want to donate for you . another one is like sending  your Bitcoins daily or weekly or whatever to another Bitcoin adress using mixer .

Use bitmixer.io :)

Donation wallet - localbitcoin - sell the coins - localbitcoin - buy back the coins. You pay the spread and incur some losses but all that would hide yourself

monero

what? did someone say something?

Yeah, I just wanted to not be the first to bring this into discussion.
And strangely, though both (BTC and XMR) prices are falling, usual people (not me) feel more confortable to work with BTC.

When you keep the same address for donations, people are always able to see how much donations you received. You need to change the donation address frequently to mask that. If you want to hide you savings, the easiest way is to use the donation address for spending only.

So, my ultimate recommendation:

Provide 2 options:

1 bitcoin address for donations, where you'd do whatever has been described above to try and keep it as traceless as possible

1 monero address for donations, because if someones really concerned with traceability they'd use a cryptocurrency with actual privacy features

and, I guess I should put it in here too to be fair, 1 darkcoin address because darkcoins all the rage these days


of course you'd have to deal with exchanging the alts for bitcoin (or deciding to hold them), but yeah.

just use mixing service to loose your bitcoin track
no one will find your real address
another option is using trustworthy exchange to hide your bitcoin chain of transactions
good luck with your donations

Create a primary address, then receiving address
After you got enough, send from receiving address using mixer (like bitmixer.io) to your primary address ;)

take a look at my current signature, the process is called mixing coins, the website explains it better though
this way your real address will be hidden and untracable

if you use change addresses, and/or every address once it is going to be hard to track your transactions and find out the source
alternatively you can use a service called mixing which you can find to mix your coins

I like how bitmixer.io recognizes TOR and has a .onion site. Has anyone done a security audit of bitmixer.io? Are there any serious reviews of it?

It will be fine, until they get "hacked".

Use a bitcoin mixing service. They act as a "middle man" to provide more anonymity to the transaction. See my signature for a link to Bitmixer.Io

That's easy and defenitely way to hide your btc ;)
why you must trade to exchanger with so many times, that's waste time and your btc because the fees ;D

Never used any mixing services but i ask: what if the coins are of criminal procedence? can you get in trouble under any scenareo or its imposible to know where the coins from?

the question is why is op trying to take donations then send them to his personal wallet?  sounds like the user is asking how to scam properly.

Dont bother exchanging! Go to Bitmixer.io and mix your coins! There is a charge of 0.5% only! Don't be greedy!  :P

Use HD technology.

You have your "master" key, from which you can generate infinite(almost) keys that you can show to each of your donors. Derived keys are unrelated, but you, as the owner of the master key, can redeem all the credits sent to derived keys.

...

For even more privacy, and if you do not mind spending an extra 0.6% or so more, you can run your BTC through TWO different mixing services in sequence...:

bitmixer.io (http://bitmixer.io)

and then

by blockchain.info (http://blockchain.info)'s shared coin service (I believe you must have a blockchain account there though).

If you are careful about doing that, NO ONE but "The Big Rhino" (US government) will be able to track your BTC.  Both above services work quite well, and clearly use different algorithms -- an advantage!

sent it to dice site and send your donation from there  (dont gamble :P )
perhaps that's one way to remove traces,.
as i do :D

Your "savings" account, has nothing to do with your "donation" account, if you do not transfer bitcoin between them.

Use seperate public addresses for both of them, and do not transfer between them.

You can check your privacy with this site -----> https://bitcoinprivacy.net/

The only reason, I could think of, why you doing this, is to take "charity" donations for your own use. This sound a bit off to me.

Yeah Id suggest these two ways as well..thats how I do it.! :)

Simple. Use an exchange or mixer service. Or split your coins through several (tens or hundreds of) addresses and return them to your address if you're bored.  :P

Alt coins are very very volatile, the altcoin may lose value and crash overnight like what happened to darkcoin before. If you use a mixer and a new address for every transaction, you would most likely not get traced.
To be honest, almost every wallet have traces of taint coins and I haven't seen anyone getting caught because of that. Since the bitcoin can also be from a exchange or other website, most people wouldn't care what is the source of your coins unless you spend a address that is linked to criminal activity to your wallet which is impossible unless you have the private key.

You go through a third party business or use a mixer.

Cheapest way to hide your bitcoin : Send your bitcoin to big gambling site, after few days withdraw it to your new address
You just need 0.0002BTC to mixing your bitcoin

Better than compared with mixing service / exchange site

Yup but gambling sites keeps log of withdrawals and IP. They are willing to give out information if you do something illegal which is possible. Most mixers don't keep any logs or delete after a few days.

Buy an antinuclear undeground bunker with a metallic safe and put an offline harddisk on and trezzor copies on there.

They are not entirely mixed because the gambling site knows what you did and keeps the information.

The OP primarily wants to hide total donations received from public.
So a gambling site should work too.

I'd suggest to make a safe bet 1.01 on directbet.. And than put the donation address wherever u want to donate as the address to receive the winnings...i think that should do the trick!

yeah mate..mixer seems to be the best way to go.

If you mix a mixer with darkwallet it should be pretty much hidden. I have no idea how DW works tho.

you don't have to use same "wallet.dat" for everything.

you can just create seperate wallets like me.

I've around 5 wallets that each one of them are used for different things. (Also I'm backing them up regularly to safe my private keys).

Separate addresses will do too.
Wallets may be unnecessary.

At times, you may spend coins from two inputs from different address by accident. This will cause people to link two different address together and your anonymity would be gone. Separate wallet.dat would be better since they are on seperate places.

Just use a mixer mixer and a mixer 3-4 times. Problem solved. You could also deposit and withdraw from a gambling site.

What for? seems like a mess.

Just send them to an escrow for holding it. Or use a mixer if you wish to remain anonymous,

I have never used a mixer but i plan to use it in the future when i being spending. ITs a bit a nnoying to run coins through exchanges everytime you get new coins tho.

I don't know the gambling site idea and the exchange to alt sounds good to me

mix your coin.

How can you be sure the mixing service isn't a honey pot? And how do you know the gambling site (or a clever 3rd party) isn't fingerprinting every transaction?

I've seen a lot of suggestions for using very weak 3rd party solutions ITT but not a single trustless solution. I believe someone here (CIYAM?) is working on cross-chain atomic transactions that would effectively "scrub" links to past transactions, but that's in development (AFAIK). 

First provide all donars , different BTC address and they won't know , they send them to some exchange and wait a little and get it together

People getting paid in sig campaigns have to always use the same signature address so the runners of the campaign can keep track and it's public. So I dont see any other solution for this than running these coins through mixers.

Personally, I would refuse to participate in a sig campaign that required me to re-use a bitcoin address for multiple transactions.

Come on! You can always move money from the account the campaign sends payment to...ideally to cold storage!

True. This is why you need to trust the operator alot. They can just say they delete logs but they actually keep those. A smart idea is to deposit from the wallet and withdraw to another gambling site and withdraw to another gambling site or just withdraw to your wallet. The probability of both of the gambling site tracking you is fairly low. Blockchain analysis might give you away if you withdraw them all at once.

That's a good idea. Do you know/trust anyone that operates a gambling/mixing site, and what are the odds that they are truly indifferent or interested in protecting user privacy? I ask just to get a feel for the odds of success.

I'd guess that just due to the nature of the problem 75% of all of these sites are either intentional honeypots or actors that could not be trusted.

If that's accurate, then the probability of being successfully tracked through two mixers (two independent events) is:

(.75) * (.75) = .5625

And tracked through three mixers (few people would take the time to do this):

(.75) * (.75) * (.75) = .421875

Four mixers:

(.75) * (.75) * (.75) * (.75) = .3164

So after using four mixers/gambling sites you still only have a 68% chance of reasonable privacy.

how does that work

wouldn't that show in the blockchain?

It will. I don't think possum is understanding the difference between anonymity and security. Cold storage only promotes security, not anonymity. It actually allows your coins to be tracked.

welp, regardless, xmr.to now lets you pay XMR -> bitcoin address, and poloniex finally implemented a minimum mixin of 3 on their withdraws, so, in terms of blockchain privacy, a good route is now:

BTC ---exchange (poloniex)--> XMR ---xmr.to---> BTC address.

granted, there may be ip logging all along that route, but that can be avoided with due diligence (and eventually i2p will be baked in to monero)

1 buy coins on exchange
2 wait for the exchange to crash and burn, erasing all records
3 profit!

Use mixer it's simple as that (bitmixer.io)

brainwallet .. if you can remember a 128bit sentence

I dont get brainwallet, its impossible to remember that many words..

Use a reliable mixer then. Use taint analysis to ensure your Bitcoin is being mixed properly.

the transaction history of your deposit  or withdrawal address are still recorded in the BlockChain! Do you think you are lucky enough to see the used exchange crash in the near term?lol

OP, why do you want to hide the received fund in the donation address? If you run a charity, Red Cross, or other type of good cause campaign, doesn't it a good practice to make your donated fund and expenditure of it transparent which will attract more donors? Otherwise you just try to scoop as much money as possible from some indecent activities?

It's just my opinion! Probably it is off topic!

Do you guys even read the thread? OP is trying to hide his coin by increasing anonymity, not trying to have better security. And also, brainwallet has several vulnerabilities.

why should we remember that anyway,

you could just write it down and put it in a random places, or create your own words for that

mixers are very probably safe. If you want to be safer, use two 3rd party websites then two different mixers.

Looks like a practical defense against all but the most serious adversaries (especially using i2p or TOR - and I'm always using TOR anyway). It's also simple and easy enough to do frequently, which is really the most important thing.

Definitely worth trying - thanks.

I hope monero doesn't get stuck in its evolution and it gets removed from poloniex, its an amazing coin.

Why would it get removed?

Well because its a passing thing like any other sh*tcoin. While there is interst in trading it, it will be listed, and as soon as that interes dusappears, so will the coin listing on exchanges.
Its happening with all other altcoin, why not monero also, its not like its any better than the rest of them, by my opinion ofc.

cheers

It depends, there are some mixers which turned out to be a scam. The coin will be under the mixer's owner control for a amount of time if the owner decides to run away, you may just lose your coins. If it is operated by FBI, you are screwed.

i think the most trust mixer just bitmixer.

But what is he function to hide your bitcoin ?

I think you meant what is the use. Bitcoin is designed to be pseudo-anonymous, not completely anonymous. Therefore, you can still get linked to your real life identity or other identity online. To prevent people from tracing the address, mixing is used to boost the anonymity.
