let's not exhagerate here.
I think it is still very possible to trade some players, even realy daytrading them without any negative effects, but not that much that huge amounts of money could be gained.
I think BB is aware that trading off 10 players or so is quite common and possible for any team. It's the teams that are trading multiple players weekly , or even daily, that are targetted here. No need to panic !!
After all they try to limit the daytrading here, not just whiping it away entirely! Keep this in mind.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
