utxo – Why is there sometimes no way to send funds to the sender's address?

& # 39; A & # 39; It has a bitcoin.
& # 39; A & # 39; try sending a 0.5 bit coin to & # 39; B & # 39;

Two utxo are created.

First, "utxo" sends "B" 0.5 bitcoin.
Second, "utxo" where "A" sends the remaining bitcoins to "A", except 0.5 bitcoins and fees.

utxo 1) A -> B

utxo 2) A -> A

The url below is the URL to see how UTXO is reflected in the Bitcoin block detector.



Sometimes, when you look at a block detector, there is TX information that you do not understand.

For the following URL, the currency in the wallet is used to transfer the same bitcoin from several wallets to another.

There is also a "TX" that shows only the amount of coins received from a wallet.

In the case of the url below, I transfer Coin from my wallet "13E3dBUWUHV8XpgJib795yqRTmyX47jWMk" and there is no utxo sent to my wallet.

utxo 1) A —-> B

utxo 2) A —-> C

If this is how money is transferred, can we know why this happens?


Get an alias address in the sender's field in Gmail

Let's say I have two Google accounts: perso@gmail.com Y pro@gmail.com.

I'm connected to Gmail in my perso account. I have added Pro as an alias address to send mail as, in the Gmail settings (Settings> Accounts and Import> Send mail as).

But, when I select the pro@gmail.com Address when sending an email, some of my contacts sometimes still see the original, perso@gmail.com address. And when checking the raw message, it seems, perso@gmail.com it is still used in the Sender: field; pro@gmail.com it is only present in the Since: field.

How to do it so that the people to whom I send the mail. Never see the address perso@gmail.com? I tried to mark and unmark "Treat as an alias" in the Gmail settings, but this did not change.
