When prices are falling, everyone panics and fears the end. When prices are rising, people celebrate and think the party will never stop. BTC will recover and likely overtake it's high, but who knows when. I would imagine this year we would see new all time highs.
if you look at the growth and fall statistics of past years, then there was no such percentage drop. At the same time, it should be borne in mind that such a huge amount of Bitcoin was not sold on the market, and there are fewer people willing to buy.
