Maybe you nay-sayers are right and I haven't turned a profit at cex.io and it is all a big scam, but my wallet tells me otherwise. I don't have a single bitcent there at the moment, but my total withdrawals exceed my total inputs, and by better margins than I described previously, so I'm happy. I'm really sorry for you if you lost money by panic selling during a drop or buying on hype during a high point. That doesn't mean that everyone makes poor decisions or that the service or price is in any way flawed. I profited through the last few difficulty adjustments from you and others who did the same.
