Step 1:
Log into your BitBuy account.
Step 2:
Select Reports from the menu on the right.
Step 3:
Click on the Download button in the bottom right corner in the All transactions box.
Step 4:
Navigate to Step 1. Import. Select Add Account then choose the BitBuy tab on CoinLedger. Click on Upload File or drag all of your CSV files into the box to import your transactions.
When importing a transaction history CSV, you will have the option to specify a start date for your import under the Drag and Drop Files Here box. This feature is designed to prevent duplicate data from being imported. You can access this feature by hitting the Import Settings drop down menu, as shown below, and then specifying a date for your import to start from. All transactions after this date will be imported. You should not do this if you are importing all of your transactions into CoinLedger for the first time.
