very strange... same amount selling every time (39876 tokens). What is this?

It's maybe people selling their 40 000 bounty less the exchange/gas cost. Doesn't etherdelta take fees from the token if no eth is available?
There have been a few people expressing their concerns in this thread. I don't know what's going on.
When you selling tokens on ED, their have fees in tokens. When you buying - they have fees in ETH. So this only fees from ED. When week hands sell their tokens. we going to 0.5-1$

What are you talking about? Who has fees in his tokens? Of course EtherDelta charges a small fee, less than any other exchange. Or what do you mean?
