This is very normal that the bitcoin has already passed the major crash and now there are some timely crash due to some disinvestments of FuDs. But the price of the bitcoin will be rising because now the countries have started preparing the bills for the legislation of the bitcoin so that the people can use this thing and can be taxed for doing different transactions in the bitcoin. I don't think the price was over rated, BTC price shoot up due to increase in demand which created more volume for the industry. Hence pushing the price beyond its normal price
