Binance just informed all of its users that due to their recent security breach they removed all API keys from their system.
Please note that no TaxBit users were affected by the hack, as TaxBit only collects read-only API keys, with no ability to trade or withdrawal assets.
All TaxBit users will however have to reconnect their Binance API key. To do this, go to your settings page, click the red "remove Binance" button, and then reconnect your Binance API keys by following the short video tutorial contained on that page.
