I was trading Bitcoin and Ethereum on Coinbase for several months, and I made some nice profits. However, when decided to convert my Bitcoin back into dollars and withdraw my funds to my bank, the sum was deducted from my Coinbase wallet but never deposited into my verified account. I have sent half a dozen emails to Coinbase 'support' over a period of weeks, but have been completely ignored. I frankly cannot believe such a blatant scam is allowed to continue operating.
