& # 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?
