Ever since bitcoin hit $1,000, they've said it was in a bubble and would soon burst. However, it has gotten to $9,000 and strongly eyeing $10,000 now. Most of this surge has been due to the several Bitcoin forks this year. I'd advise bitcoin owners to hold on to their bitcoins, but for those who don't own any cryptocurrencies and looking for where to invest, better to look at Ethereum, Litecoin and Ripple.
Bitcoin would definitely hit $10,000 this year, but I can't be quite certain it would get to $12,000.
However, looking at the way things are going for bitcoin right now, you never know, it just might.
