please I need some help in reading the hash data correctly. Given below transaction of total value btc 1.55821903 https://www.blockchain.com/btc/tx/8bbae353ce95fb0a6cbff44b8dd1c3cdd7d6419e0c63ee73f59db7cc0c110dc1
Only btc 0.00621581 were effectively received by B (recipient)?
The amount come back to A (btc 1.55200322) was not sent to B at all?
Therefore, can A say "I paid B with btc amount 1.55821903" in any ways?
Many thanks to the community
