I am an EVM blockchain engineer and I started learning Bitcoin few days ago.
this is my friend’s address of bitcoin wallet: bc1pfatr7dvkz65y6p6xxv84anesttxc7q9etez8em5uyvll5kk8atpqrx3r2s

and what makes me confused is a transaction in his history. https://mempool.space/address/bc1pfatr7dvkz65y6p6xxv84anesttxc7q9etez8em5uyvll5kk8atpqrx3r2s

the very first transaction is understandable.
there was no transactions before first transaction and bc1q7pcfjas8swacpwnmm5d4s679jffn3lawkm89kv sent some amount of BTC to this wallet. (It’s okay)

but the next transaction is strange.

1. why there are two outputs that is same as wallet address?
2. and what is the meaning of this green button?
