It does not appear to work as you guys think.
Bitcoin in the old days did not use to do this.
When I was sent bitcoin to an address, it STAYED on that address. I could always go on blockchain explorers and see my funds.
-snip-I wont point you to technical explanations like "
there's no addresses in the blockchain" to keep thing simple.
That's just clients lacking the use of change address, even if it's sent to the same address, it still the same as sending it to a change address.
That change will be a UTXO that your wallet will spend in the next transaction.
So you basically used 1 coin and gained 1 coin either way.
Seems like you're pointing your frustration to the wrong feature because having more UTXO to spend just means that you've been receiving lots of transactions.
