Coinbase is a complete scam! I placed a limit buy order considerably lower then my higher limit sell order and Coinbase somehow refuses to acknowledge profit. When I finally got an online agent to assist me, I was asked for my transaction id’s and date of which I provided and of which show the profit. Yet, agent, which has no clue about anything related to trading and is relegated to cut and pasting what she thinks is applicable, while at the same time ignoring the blatant proof of my transactions, is of no help whatsoever. These people are clueless, don’t care, and system is designed to steal your money!!
