For the past few weeks, other than rapid drops in price for both Bitcoin and Ethereum. Ether had a drop today for over a significant amount of backlog on its network. I watched the trades drop significantly to the point of even $13 for about one minute. That blew my mind sideways! As soon as that happened, Coinbase served its slice of frustration. In the past, the company has been notorious in the community for shutting people out from their account balances. Not to mention, their customer service rep's are total ludacris who don't respond to emails promptly.
It is an absolute mockery to manipulate the market this way. I would not recommend anybody to keep money in their hands unless you are willing to take the risk of losing your investment, or even a good trade, and I know people don't like bringing up Mt. Gox but this sure does smell like it. Prepare adequately!
Step 1. Get a Cold Storage or Paper Wallet
Step 2. Safe Keeping
Step 3. Happy Life
