More realistic view of achieving 10 000 usd/xmr is 10-20 years. It took 10-20 years for internet to break through so please give Monero also some years.
20 years is really a long time in terms of software engineering, so I would not expect that Monero still exists in 20 years in its current manner. I think good software will succeed in the end, so I'm holding my Moneros as long as necessary (long term investment 2-5 years).
Regarding the zCash hype: I think a lot of people will loose a lot of money in the the first weeks of the zCash launch (every bubble bursts in some time). So I will stay away from zCash. Although it's not a design contest, but the zCash GUI looks really ugly
It is.
But Monero is much more than a software. It is a digital currency. The rate of change will stagnate as well... In the beginning we see the largest changes taking place, later changes are just fine tuning (like SD cards - in the beginning they were a big thing but later the only thing that changes is the size of the card).
I think there will be new applications for block chain, Monero but I do not consider them as threaths to the existence of Monero. Just like Etherium is not a rival to Monero but it fills a niche that Monero or bitcoin cannot fill anyway.
