Bitcoin is the #1 unpredictable asset in my opinion. Tell me if you'd ever believe anyone telling you that bitcoin would climb from $5k to $50k within a year, because I wouldn't! I'd think that it's just another bullish article-site that wants some traffic and has ran out of ideas.

Predicting how many dollars a bitcoin will worth in this year, assuming you mean ATH, then I would say above $90k, just like it did with $9k. I have no idea when will this happen, but I believe that this will be a really good summer.
