Amsterdex? You seriosly? Who heard anything about this exchange? As a result no one bid on this DEX.
New exchanges pop up at a rate of 10 a day because it is easier to make a scam exchange and run with the money than it is to make a scam ICO.
When the community got Helium listed on Amsterdex I wasn't completely convinced as well. I spoke a lot with the people behind Amsterdex though and they seem serious and competent. Hence we post it as a considerable option.
