I actually dont know how to compile anything.
There should be something like ticking a box to start out exploration over a Gui wallet.

NEM is a peer-to-peer cryptocurrency and blockchain platform launched on March 31, 2015. Written in Java, with a C++ version in the works,
which is a Excellent Project....

Long back I was also trading with the small amount with an unverified account but one day suddenly they didn't allow me to withdraw my coins. The total worth was around 0.1 BTC and when I contacted their support team they ask me to verify my account first then I can withdraw my coins. Luckily my account got verified within seconds or almost instantly after uploading my documents.

So if your using unverified account with bittrex then be careful they may ask you to verify your account at any time.

Yes, Bittrex doesn't have fiat trading feature.

they only accepted new users for like 20 minutes...

Ah well. At least it's a sign of ongoing demand.

They sure do have a new look! I had to log in just to check it out (and maybe buy some more XEM). Fortunately for me, you can switch from the default dark view to a view that is more like the white background I'm used to. There is a light button in the top right hand corner.

They still have the register button on their home page. Hopefully they can take on a bunch of new users.

I am glad that bittrex again accepts new user. Anyway I wouldn't keep a large sum on the exchanges too
