I'm starting to think that there is a group at here. And it's members are trying to spread fud to decrease the price.
I think the group wants all XST.
That's exactly what's going on.

Whenever you see a bunch of people pop up in a thread (that have never been there before) and all they do is talk trash...they are trying to scare people into dumping cheap coins. It's the oldest trick in the book.

Part of the reason is Bob, who attacked other threads touting XST and trash talking other coins (probably to get more buyers so he can dump), so people who didn't even know of XST took notice and decided to give back the favor. But too bad they don't realize Bob is probably gone already.
I already know who dumps on the last round, he turn his 5BTC to over 120BTC, it's time for him to move on perhaps buy a gold dildo for his wife. We can't blame him, the core of Stealthcoin is Stealthsend and after that is OpenBazaar and an openexchange also in discussed. Stealthcoin is going to be a huge success by next year.
