Vector has already locked in 5 orbital launches starting in 2019 with Open Cosmos:

But then when a whole lot of attention was aimed at it, and it started to actually prove to have utility (when really useful ICOs started rather than that DAO fiasco) and worth and the price started climbing. It then hovered around the $50 range, which is unfortunately for me - when I sold most of what I mined. I did make a nice amount, but if I had HODL'd it, it would now be worth a quarter million, rather than the approximately $12000 I made.
Hindsight is 20/20 obviously, and I had financial pressures that more or less forced me to cash out early with ETH. It was so nerve wracking for someone like me who isn't very rich or wealthy - and the electricity bills on the mining rigs were ridiculous because I live in a VERY energy expensive country....
but the point of all this whining is: HODL your NXS if you really believe in the project!
I'm not sure about it yet - obviously it has great ideas, but I'm very cautious in my optimism about it because it seems almost too ambitious. I work in electro-mechanical engineering so I know how expensive and time consuming it is to build very small but highly functional devices - so I can only imagine that just building a cubesat, before you even get it on a launch vehicle will be REALLY expensive. This project is proposing a constellation of these! Imagine how much money it cost to put up (and maintain) the GPS constellation!
I think that if Nexus manages it's own "Sputnik" and actually succeeds in having one up there and working - it's price should just head for the moon, and then I guess that's how they fund a whole constellation, so IMHO - successfully Earth orbiting a nexus node (or not) is the whole deal. If they can do that it will be in the top 5 on coinmarketcap.com, but for as long as they don't the price will continue to fall.
I guess it's possible that if they show in public that there is progress towards this goal it would definitely pump the price - but maybe they don't want that to happen. Or maybe it's never going to happen because there is no progress towards this goal and it's all snake-oil like 85% of crypto currencies - I haven't done enough research or actually seen any evidence that makes me confident that this is real yet, but I do HODL a few hundred NXS. Right now I am very, very tempted to buy a whole lot more in the hope that this is real.
Good luck Nexus - I hope you really can make "skynet" but for all of us to benefit from - rather than the other thing.
