OMG WTF guys? I`m getting scared.
So if i just send now a transaction, then i lose my bitcoins and it doesnt get to the other end?
Also what if i buy now bitcoin with do i get fake bitcoin if the merchant is on wrong chain?
This could be a serious problem. No FUD intended but seriously, i`m starting to panic/

Just relax. Why would you panic at all? Obviously you're that kind of person, so how about you just pause everything related to Bitcoin for a day or two?
You don't buy Bitcoin from merchants, but rather on exchanges. Even if something does go wrong I'm pretty sure that Bitstamp would reimburse you.
We just need someone to confirm this. I think that everything is fine now, however I can't be sure.
