Why publicise your wallet address

[decodx]

...
So, what really is the reason behind wallet address publicity, is there a transparency to be proved or something else?

You may choose to hide your address to help prevent others from tricking you, and for your privacy.
However, there are a few reasons to provide a wallet address in your Bitcointalk profile:
- You may need an address if you want to receive tips or anything else in bitcoins or some other currency.
- You may want to prove your liquidity if you are engaged in some business on the forum, for example, lending, currency exchange or escrow services
- You may want to protect your bitcointalk account from theft or hacking, so you can sign a message from that address

What necessitates wallet address publicity?


Is it really necessary to put it up in your profile?

No its not necessary but there are advantages as posted by the others above.

Its also useful if you are doing business on the BCT forum like working in signature
campaigns. When applying to a campaign and looking to list your address for payment,
instead of having to login to your wallet your address in your profile is ready for that task.
Its a small thing but it can be convenient.

I actually see it the other way around: logically, public addresses are required by campaigns to fulfil the payments, but they also contribute to being less pseudo-anonymous globally. The more visible these public addresses are, the more transparent with the payments and such, but also the more information that builds around your account and that becomes of public knowledge through tracking Google Sheets, postulating post to join the campaign and so forth.

Ideally, all this should be carried out in a much more private manner which I’m sure can be thought of.

When concerning transparency you can't really have it without compromising privacy in some sort of way. However, I'm not sure how much transparency is needed when concerning the payments of the campaign. Generally, people only care about if an individual has been paid, and not how much the campaign is sending in total. So, you could potentially get users to sign up without an address, but by doing so you make it harder to prove that the campaign has sent you money, especially if you want to keep your addresses private.

I'd probably be in favour of changing the way sign ups for campaigns work, and not broadcasting your address to the world upon sign up. However, having that transparent system has worked in the past for finding cheaters of the system. So, there's definitely pros, and cons to the system. Really, the people behind the campaign should probably be on the look out for people cheating the system, and would have all the addresses. However, as the saying goes two heads is better than one, and by having the addresses public you introduce a lot more that can do the vetting for them, without needing to pay someone to do it.

Addressing specifically the payments made by campaigns, there is indeed that double side to the sword (the more public the more transparent and ready for lateral actions such as catching cheaters, but the less private in relation to the account’s crypto tenancy).

I’ve come to conceptually favour privacy there though, and just as there are campaigns that display a wild array of personal contact information (emails, social contact channels) that could compromise the account’s anonymity at some point or else, so can published public addresses tied to campaign payments lead to some unwanted ties at some point. I’d favour privacy over catching cheaters really, and assume that payment disputes do not require making available everyone’s tenancy from the campaign.

Note: mind is going Big Data here.

@Mr.right85
I don't know if that Coinremitter signature you are wearing is because of an advertising campaign or not. But if it was, I could easily track your addresses and see what you are paid, and where and how you send those funds. You can do the same with me or any other member of the forum. Considering, of course, that both our campaigns have public spreadsheets, and in 99% of cases, they do.

From a privacy standpoint it's not the best approach, but if the forum and the campaigns advertised on it are to remain completely transparent, it's needed. Thankfully, we have services like ChipMixer, CoinJoin, or privacy coins like Monero which can all be used to cover your traces.

People have a different reason for publicizing their wallet address through their profile, I think the number reason is for payment receiving on the forum cause most of the wallet is already staked on the forum and I don't think there will be any danger though cause most of the wallet owner move their coin asap but there's still a chance for vulnerability cause using a single wallet than 3 times is not advisable.

Although I do have an address in my profile, if/when I receive money in that address I change the address. And I advise everybody do the same.

Your advice is good advice if not a little bit extreme. The majority of people would probably just benefit from putting an address in their profile specifically for this forum, rather than changing it every time they receive Bitcoin. Maybe, if the amount begins to stack up, and its more money than your comfortable showing to the world, then you could change it.

You do have a point, but in my 7 years on Bitcointalk I've received money into the profile Bitcoin address maximum 3 times. I tend to believe it was only once, so the 3 is "to be sure".
So unless somebody is involved in businesses on the forum, I find my rule is as good as yours.

I had previously rarely change addresses because each address I have replenished the same sources. Now every time I change my address, or rather its change purse itself.
