Crypto Bubble?

With the transition to digital currencies becoming more and more popular, the question has risen: Are cryptos – i.e. Bitcoin, Lite-coin, etc. a phase?  A bubble that is going to pop?
My initial inclination back in 2010, was that they may be.
However, they continue to grow as a safe haven as a store of wealth.
The more I look into the subject, the more I realize that they are changing the world.   Many countries are now adopting them as trade-able currencies.
Bitcoin has risen from about $600 to over $4900 in the last year.  It seems that the world is changing, so in my humble opinion, it seems like time get on board the crypto-currency train.
