Okay here’s my advances so far (Warning Experimental!) :-
Create ‘Binance1’ and ‘Binance2’ wallets.
1=Basic transactions i.e. buy,sell,deposit,withdrawal and fee.
2=All other exotica such as liquid rewards, referrals, savings, dust, commissions etc.
Populate wallet 1 then wallet 2. You should create separate derivative csv files for each set of transaction types to export into the Koinly wallets.
This has reduced, but not eliminated my missing costs. Mostly it is ‘Small assets exchange BNB’ dust issues remaining, but some totals are wrong now, so…
Anyway it seems helpful to me to split the data into managable/incremental stages for error analysis and any removal/backtracking needed to fix stuff, even if it comes out wrong. Let’s Go Crypto!! Yay… ;-\
