Tell me why should one buy this coin, 
You are asking investors to supply a phone number to join your discord 
This is one investor that will not go and invest in a coin who wants to invade my own privacy, yet will not supply the developers where you want my money.
Next, you will want my passport particulars, Nodex coin I bet your own devs are hiding behind there computer screens also.

https://nodexcoin.org/ read this and where is a white paper its cheap and nasty and straight out looking like a coin that will take your funds

Be Aware everyone this is a high-risk coin and I recommend to Not invest in it.
One can not see the developers faces and this Master Node stinks of a scam like most of the master nodes.
