The digital currency just hit the $14,000 mark for the first time in Asia Thursday.
Back in 2011, it was worth less than a dollar.
And it started this year below $1,000.
But by last week, it shot above $10,000.
Now Bitcoin is attracting the attention of economists.
Some describe the rapidly growing currency as unstable--but others say it's only up from here.
