My advice would be to buy 1/2 of what you want to invest now, and then buy the other 1/2 if this comes down or at least before it goes up, by that, you can reduce average cost, and also you dont miss everything if they go up soon.
Advice is to sell this coin,this is dead project and just pure speculation about price.
I am hearing what you are saying, fortunately I bought when the price was quite low (not the $6 USD trading started at). I am going to hold onto my MN and just see where it goes, fingers crossed the dev comes back to public view with some idea of the future of AGNI.
