For bitcoin to reach $50000 this year is quite impossible to achieve after its deep drop from $19500 down to $6500. Recovery from its previous all time high will really takes time, and how much more for the expected $50000, though I am a believer that bitcoin value can really go much higher but it really takes at least a year or two. What I wish will happen is for bitcoin to go back to $19500, that's good enough for me.
It doesn't matter how much deep bitcoin gets, once the bullish run of bitcoin started even in just an hour we'll see a significant price increase and it happens a lot of time before, if you follow these correction trends i think $50k at the end of this year is not impossible.
