I gave Coinbase a few days to respond to my concern.  Nothing - so here.

To Coinbase
a616959e46b0cb66eb8b0d2bd5ab9f4b87a28ffdd430a29f90d41b0767242a29

After 24 hours of 0 conf - From deposit address to Coinbase owned address
3386c6a7fa2d58a6b62db22319fecb820bf4d04a0f775558ac915ec1343b7a7f


In the end, the TX's were confirmed - BTC went in - it went out, balance credited, then debited.  No BTC.

The deposit TX byte size was huge, 7 kB ish.  The fee was low, makes sense that conf stalled.


Lovely.
