It's hard to say, maybe Bitcoin and other currencies will co-exist, does it worth more? Maybe, depends on what will happen in the near future.
I can't say I'm not happy that Bitcoin price is growing every year! I believe price will be stable around 1000$ next year.
Bitcoin is very important especially to us in internet. Yes, I believe so that bitcoin should be quite stable with only minimal fluctuations. But this sudden Jump and pump sometimes sending panic to sum.
