Recall the crypto meme "Neo: What are you trying to tell me, that I can trade my bitcoin for millions someday? Morpheus: No Neo, I'm trying to tell you that when you're ready... you won't have to." 
Historically, every fiat currency has gone to zero, eventually. I personally believe that there is more risk of the $USD going to zero than any major crypto. When that day comes, I want to be prepared.
NEO is on sale today $9 :D
