I have seen more then one of these posts in the last a few weeks and as you can see, Its 24 days old so the price was not even this high back then.

The price at Preev.com at the moment I'm writing this post is: $4452
This means that you are paying over 48% of the regular price! I would say that this is a straight attempt of stealling users.
$6600+ for 1BTC is extremely expensive, what do they think they are doing, are all people bitcoin or only they know how to earn fast money by selling bitcoin for a ~+50%. By selling 2bitcoins they can buy immediately additional 1 bitcoin which is the fastest, clearest way to earn good money which the customers don't like this. I have never use shapeshift or changelly but this price is not fair.
