Agreed. Even if payment were made from an escrow account, into a PayPal wallet, in a way that is disconnected from the original Bitcoin transanction,  there is still a real risk that the payment could somehow be tied to the transaction, including one's sending address - revealing one's identify.

So, it all boils down to method of payment, which makes inperson worth focusing on, but keeping in mind the risk mitigation measures.

Regarding voucher and other intermediary routes, it is back to square one, involving a potential loss of value in the original asking price, in order to make an attractive offer for a quick sale.

I understand, thanks. Also, is there a way to receive the asking price in PayPal, without connecting my identity to the transaction and therefore, blockchain?

Thank you very much for your helpful suggestions and links. As a seller, is it good practice to add to the fiat equivalent, sending fee (from Electrum wallet) and trading fee charged by the platform (i.e. fiat equivalent + sending fee + trading fee = fiat received)? By strict privacy, the idea is to avoid any connection with fiat or fiat-related payment system - a clean separation between personal id and the blockchain.

Point taken, switch to Electrum wallet has been added to my last post.

Thank you all for the great help. I now have Electrum wallet.

My next challenge is to convert some bitcoins to local fiat currency with strict privacy and at little or no cost. I expect to add Electrum sending fee, and other costs (e.g. exchange or other intermediary commission) to the fiat equivalent. Is this an acceptable practice? Your suggestions would be appreciated.

I understand that Electrum charges a flat rate fee.  If so, could you please help with these -

• Is the flat rate fee 0.2mBTC or 2mBTC, mBTC meaning milliBTC or one thousandth (1/1000) BTC - as if Bitcoin and cryptocurrency generally were not complicated enough.
• Accordingly, 0.2mBTC or  2mBTC means 0.0002BTC or 0.002BTC (~6USD or 60USD)?
• Are there any other additional fee?
• Does any Electrum fee apply to all transactions (i.e. receiving and sending Bitcoins)?
• Any other thing I need to know about Electrum mobile wallet?

Thanks for your reply. Briefly, how do I verify Electrum mobile (Android) wallet signature specifically; and what is "BIP39 seed phrase"?

Thanks for your reply. It is helpful to know your thoughts about the "Sending addresses" tab. It would probably be active and slideable, as you suggested when the tab becomes populated with sending addresses. Quite right, Electrum is the most likely  other side of the coin - so to say.

No, I am not complicating things at all; but please simply read my post in the context of the original post and following welcoming reply by Lafu. The issue raised was how to activate the greyed-out "Sending address" tab within the label tool.
My comment you refered to was just a confirmation of my understanding of Lafu's solution.
Please understand that the marked bottons are not shown in the downloaded wallet, as mentioned earlier - which is the crux of the issue raised.

I meant in relation to and the context of the greyed-out "Sending addresses" tab within the 'label' button of my downloaded Bitcoin Wallet. However, I now understand that sending addresses are the recipients' receiving addresses and that aspect of the issue has been solved.

The downloaded mobile wallet is Bitcoin Wallet 7.69, like the one below link points to, but without the 3-dot settings button.

I expected the wallet to generate the seed phrase automatically, as you described; but that is not the case here. Any more ideas?

The current issues are listed below.

• Bitcoin Wallet 7.69 seems to be the highest version compatible with my Android device.
• Why the settings button (3 dots) is absent in the wallet and whether there is a way to recover it.
• How to get the wallet behave as expected and generate seed phrase,  etc.

Your continued support is well appreciated.

Thanks for your replies.

I see. So, if "the sending address is somebodys receiving address", it follows that my receiving address is somebody's sending address - right?

As to the private key, the downloaded mobile wallet is "Bitcoin Wallet", but without 'settings' (the 3 vertical dots).

I can only see the Bitcoin standard 'label' and 'payments' (3 descending horixontal lines/dashes) icons/tools at the righthand corner; and the "REQUEST COINS" and "SEND COINS" with camera icon at the bottom, and footer "safety notes" link.

In other words, the wallet has the standard Bitcoin Wallet layout (see link below), but without the '3 dots' at the top right corner.

Hi,

I have downloaded Bitcoin Wallet on an Android device. The wallet generated a receiving address automatically as expected, but the "Sending address" tab (within the Label menu) remains greyed out - presumably, until there is Bitcoin in the wallet to send.

So, the question is this: how do I get a sending address and private key before backing up the wallet and receiving Bitcoins?

Your help would be appreciated.

Thanks
