I haven't spotted anything.
I do not think it's realistic at all. $1 XEM could well be but the NEM action seems to be happening mainly on private chains and there comes a point where that hype can only go so far. ETH will find out the same thing eventually. The things they're planning won't come to full fruition in a year and a bit.
You won't find me objecting though.
Would also be very surprised and in the same time happy to see 5$/XEM . I guess the range will be more around 1.5$-2$ if NEM continues the solid stable work development. 5$ possible when "competitors" screw it more and more up, like we can see now...
All we need is time. Compared to other companies/industries/stocks/markets/etc ... 90bln total market cap is just so tiny.
Massive world adoption for cryptos will come, I am sure.
I think so too. This is just the beginning. there will be general constant growth with hypes and down in between ( some nice opportunities for crypto-enthusiasts to make some additional gains), but general always up. As it has always been: the patient ones will be rewarded
