Still can't see the point of bidding hundreds of millions of dollars for a player worth 5 million. If it's just to transfer money between accounts, what's the point in having over $2 billion at level 4 or 5, there's nothing to spend that sort of money on.
It must also leave the team from the "sub" account which must be at a higher level, with no money and no chance of improving anymore. Why bother moving this sort of money to a lower rated team, makes no sense.

This does seem a very easy way to waste a huge amount of tokens. Only winner I can see from all this is Nordeus.
