Looks like the year 2021 for BTC was a roller coaster ride whereas with there were major ups, there were so many downs too. But the year 2021 didn't end on a positive note for BTC as it didn't manage to get over $50k area. I believe we may see more downside in the near term as there is enough fear (I know markets go up when fear is high, still my inner sense says that it'll drop).
it's true bitcoin failed to reach $50k at the end of the year but I don't think this will affect bitcoin's record in 2021 because at the end of the year bitcoin price is not far from $50k. I think 2021 is a really great year for bitcoin because in 2021 the price of bitcoin rose very significantly and recovered very quickly, and this caused bitcoin to hit its highest price twice in one year.
