Just profit taking in my opinion. Bitcoin along with the entire crypto market had a huge run up over the past month. The total market cap went from $250B at Thanksgiving to $625B 4 weeks later. It is only logical that some people took some profits. This is natural for markets, they rarely go straight up...there are always pullbacks along the way.

As for BTC price, I see it above $50K by the end of next year. Wall Steet is really just entering the picture and it loves Bitcoin. For all the technical/scaling challenges bitcoin has, the name and liquidity will keep it the darling of Wall Street.
