5 days ago, Trade.io opened up its trading platform (originally slated for May), however the price continued to plummet from as high as $1.70-$0.15 as of the moment. So its pretty obvious that they are spamming the hell out of the forum to create another hype on their platform.
Although, this might look like its the case. There's no actual proof of this. Normally, these types of advertisement spams are offering a reward to its users rather than spamming themselves because its much more efficient. Plus, because there's several accounts which have been registered for a few months, and have suddenly started posting the advertisement spam I think that they may well be offering some sort of bonus.
I haven't researched in enough depth to see if this is the case yet though.
