This. Exactly.
For those who can't handle this concept here is a simple solution:
1) take the amount of bitcoin you are comforable seeing be worth nothing (yes absolutely nothing) someday
2) put the bitcoins from #1 on a paper wallet, multiple backups, safe storage, etc.
3) sell all the rest of your bitcoins
4) wait 10-20 years.
Tada the growth rate will be much more "managable" and with massively deeper markets the intraday volatility will be much lower. Either that or Bitcoin will be worthless. Still the problem is solved either way.
Those worrying about the rapid growth and volatility likely would be trying to plan the growth of the internet circa 1972. "see we just connected the first two nodes. We anticipate 100 new nodes to connect to this "internet" in the first year ......
WTF MAN? 100 nodes per year? That is like 5000% growth rate. BUBBLE, TULIPS, PARABOLA. You internet idiots don't know anything about stability. I going to do make my planned internet. 10% growth per year and minimal volatility. By the year 2202 finally all 7 billion people on the planet will be connected to the planned-internet (although only 4000 in the first 30 years). It will be a perfect no volatility line from 2 nodes up to the entire planet.
Which likely would have worked out better:
a) the chaotic explosive growth internet based on the free market.
b) the centrally planned internet based on a stability plan to minimize volatility and manage growth.
