so someone is selling tokens/btc cheaper than ico price on BTER
It might be arbitrage. They might be buying and selling in BTCD, NXT, and BTC. They have figured out a small way to beat the system. The prices of each of these coins are going in different directions, up and down.
Could just be somebody is scared.
By they, you mean the operators, the guys that control this IPO. Believe me, if they wanted to disable trades they would done that already. This ipo is fishy.. and weird.
No, considering it's already been stated that the IPO will go for 14-28 days depending on demand. What is fishy about that?
And they decided to allow people to sell their TOKEN below the IPO price just in case they had buyers remorse or needed funds for a personal emergency or something. It was actually quite nice of them to allow this, but of course the accusations of foul play never seem to stop.
