yes. those 0.00018 btc which i received from my friend is now showing as spent. you mean now my wallet has 0 utxos?
UTXO stands for Unspent Transaction ("TX") Output, which means as soon as the UTXO is spent, it is no longer a UTXO, we call it a spent transaction output.
So your 0.00018
BTC UTXO has been spent, and the transaction in which you spent it has created two more UTXOs: One of them is the 0.00006
BTC coin that you sent to the other address, the second UTXO is the 0.0001
BTC which your wallet has sent to a special address inside your wallet (as I mentioned, this is called a change address) and can be viewed if your wallet allows you to view change addresses.
Would you mind telling us the name of the wallet software you are using?
