So, here is a record from LATEST TRANSACTIONS in my waves wallet at https://waveswallet.io/
Date: 10/22/2018
Type: Incoming Mass Payment   
NAME:   Bitcoin
RECIPIENT:   n/a   
FEE:   0.051 WAVES
UNITS:   0.00011680

However, when I go to my portfolio in the same wallet, it shows 0.0000408 bitcoin.
How come my total bitcoin is less than what is arriving?
I dont where the bitcoin is coming from.
