Bicoin to Coinbase now has a threshold?

It's not a big threshold admittedly, but I thought if you had 'Sent to Coinbase' turned on, it would send any amount?

I thought so as well. Any transfer within the Coinbase eco-system should not have a fee, at least that has been my understanding.

There is no payout threshold for any Coinbase transaction.

If you think you're seeing one, then please submit a support ticket and we'll be glad to start an investigation.

I'm seeing the same thing with other coins but seems to only appear when their balance is under $0.01 - even if it is a Coinbase coin.
