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. Currently market is showing no signs of recovered and it seem to remain down for the coming days also, one can hope that after march and one can expect market to gain some momentum and show proper signs of recovering.

One or the other day the value would recover back. Its taking bit long time this year. Hope to get back on track soon.
