I'm quite confused about the input count that affect the transaction size, example:
x1 = my receive btc address
x2 = my another receive btc address
x3 = my another receive btc address
Scenario A
P1 send 1 btc to address x1
P2 send 1 btc to address x1
P3 send 1 btc to address x1
Scenario B
P1 send 1 btc to address x1
P2 send 1 btc to address x2
P3 send 1 btc to address x3
So my wallet will have total balance 3 btc.
My question is when I try to send 3 btc to P4 (Another user), scenario A will count as 3 inputs or scenario B will count as 3 inputs or both is same 3 inputs?
