Well I paid like 0.001 BTC or 0.0001 BTC cant really remember,
I sold for 2.5 BTC.
So no complains here

EDIT:
I really don't understand why people keep buying those,
Nem people talk a lot but delivers nothing...
You really did? I'm surprised. I've missed out on this completely. Well it will always be like that, promises are being made people blindly following and buying up the coin.
I do not really see the need to buy NEM, nor have I ever. Although I've seen a lot of NEM supporters a month or two back in various threads.
