In my opinion it is a great testimony that we just crossed 100,000,000% value appreciation 
It is truly amazing. What historic assets or companies have risen that much? Are there others?
I would say, no. It is "easy" to have a 1000x value appreciation with startups, perhaps 10,000x is possible. 100,000x hardly.
A MILLION TIMES INCREASE IN 4 YEARS 10 MONTHS IS A NEVER BEFORE IN WRITTEN HISTORY EVENT.
I am not surprised, Bitcoin is the first significant asset in the history to have its price completely decided by the market, thus the meteoric rise, think a moment how many folds will Google's stock price multiplies had they IPOed at near $0.
