I am switching my Bit-everything to the hodl bin... working with LTC instead, so much less drama and issues. ETH & BTC are too sporadic for me.
Coinbase.... I wrote yesterday: https://steemit.com/bitcoin/@kyusho/trials-and-tribulations-on-coinbase
About a client who paid for an item with BTC, transaction still "PENDING" from December 12th.
I wish there was a similar purchase, sell, transfer option to Coinbase (with merchant applications)...I would switch in a heartbeat.
