Why do you say that this correction is looking to big? I think it's perfectly acceptable that the bitcoin price went up the way it did, since it was getting major awareness, and now that the awareness factor has passed away, bitcoin will need development improvements to rise again, or real changes regarding regulation or finance markets integration. Until then, it's perfectly normal that people are not buying anymore, and those that don't really understand the coin and it's potencial will probably sell it now for profit, or maybe in a loss for a lot of cases. Only those that know what are the future plans for bitcoin (like ETFs and lightning network that will allow global adoption and use) will hold the coin. Those that only see it's price, are selling right now, only to see that they bought at a temporary top, and sold at the very bottom and lost money.
