Rather interesting project going on here.
I think the potential upside is huge if this catches on.
Compared to anything similar NXTTY is miles ahead already in terms of delivery on a real functioning product.

It's refreshing to see solid innovation here compared to all the drama and false promises occurring in Crypto right now.

And in terms of the market :

It's just a gorgeous chart looking at the 90 day. From $175k to over $2 mil.

WhatsApp for $19 Billion and NXTTY only at $2 million = Lot's of room to grow
I don't think a $20 million dollar market cap is unreasonable in the not too distant future.
