Thank you all for these answers.
In the meanwhile I bought about 20000 NXT.
Whats your opinion about NEM, EMunie and Ethereum?
Don't waste your money. Just buy more Nxt.
Don't waste your money by buying NXT - as you ALL can see NXT is going to
die!
Buy something with an expected future ! Invest better in BTC, LTC and if you would like to invest in something big and new, buy NEM after ETA.
Probably this will be THE BIG THING this year.
