Ladies and Gentlemen, step right up. What I'm about to tell you is both mind blowing & market shattering. I'm calling Coinbase's bluff.
They can't handle the amount of volume coming their way. Instead of manning up and admitting it, they're using it as an opportunity to cleverly self promote in a most disingenuous way.
Today the price of Ethereum on GDAX went down to $13, but did it really? The answer is NO. They admit that NO transactions actually transpired at that low rate. It was 13 in number only for promotional purposes.
They did this in April as well, putting the price of BTC @ six cents while they were down for maintenance.
