This sounds weird to me, are you reselling NET after getting it yourself from the crowdsale?
It's not weird, it's smart. They've spent lets say 30 ETH on acquiring 4725 NET. (exact numbers aren't important)
Now they sell you 60 NET for 1 ETH, so if you want to buy all their 4725 NET, it'll cost you ~80 ETH. 50 ETH easy profit.
And even if they don't sell any of their NET-s, they still have a fair chunk of a promising startup. There is nothing to lose from their point of view.
