Crypto currencies and high volatility that continues to drive impulsive investment behaviours

After the breakup of Bitcoin into two different entities, the crypto currencies world has seen some really dramatic fluctuations, is this trend sustainable in the long term considering the extreme volatility of crypto currencies or is there going to be a major correction in the near future that will see some relative stability?
It seems the lack of stability continues to drive huge profits and overnight losses but not able to allow for long term planning, only impulsive behaviours.
