so if im accumulating btc it doesnt matter if im receiving on one adress or different adresses right ?
It does matter. You can consolidate small UTXOs from one address, but cannot do so from multiple addresses.
How bitcoin works is that each transaction is considered unique and stored separately on the chain.
If you receive $30, $50 and $20 into one address totaling to $100, you have 3 separate inputs. If you want to send $80 to someone, electrum can choose from 2 or the entire inputs to make it up. You can control this using coin control.
Coin control allows you to select the $50 and $30 inputs for the transaction.
If you do not do this, the system can choose the $50, $20 and then $10 from the $30 input, leaving you with a change of $20Why it matters if you receive into one or multiple addresses is that you can consolidate all 3 inputs by sending them to another of your wallet when fees are very low, so you will have just one input if you want to send out later when fees might be higher.
