CryptoCurrencies are getting crushed! A correction or snowball affect?

Hi Steemians,

tough day today, as cryptocurrency prices  plummeted sharply. 

Bitcoin, ethereum, ripple down more than 20% from record highs

 Is Bitcoin going to go up tomorrow? It's a supply and demand...if people will panick and sell, it will go down. If more people see it as a buying opportunity-it will go up. 

What do do you think? A small overdue correction or a snow ball affect?
