Despite Bitcoins impressive annualized returns since its inception in 2009, the reality is that the currency is still in its infancy and no one knows whether it will really become globally accepted or whether it will eventually disappear. This uncertainty surrounding Bitcoins future is reflected in its price volatility.
There is an old saying in English. It is like this:
What doesn't kill you makes you stronger. If Bitcoin survives all these latest scaling issues and problems with delayed confirmation, then it will once again emerge as the most dominant crypto-currency. I don't know whether it will get globally accepted or not, but the user base is going to increase rapidly.
