Let's think about this for a minute. Historically, bitcoin (and other cryptos-though not all) has always rebounded and surpassed it's previous all time high. All you have to do is look at the historical data. I don't think there is currently a whole lot of evidence that makes the future any different. I suspect it will eventually exceed 19k again-though I don't know when. Maybe it will be this year, maybe next-who knows?
