i have a question for you. I have checked my refereals and I have noticied that from an user I take 0.00248304 BTC of commissions (is a very old referer not active now, < 2016 year) but in my history there isn't any transaction of this import (or similar import) from blockchain wallet. How can i find the transaction of this movement(s) ?
I don't think we keep records of withdrawals that far back. Just because you earned 0.00248304 doesn't mean it all came at once it could (and probably was) lots of small amounts over a long time.
