Will Bitcoin become worthless? It's hard to say. Neel Tushar Kashkari, president of the Minneapolis Federal Reserve, believes that Bitcoin will still be worthless in 12 years; it cannot become a viable currency. In fact, the value of Bitcoin depends on how many people, goods, and services are willing to accept it as payment. If there are many acceptors, it may appreciate; but once the number of users decreases, it may depreciate or even become worthless.
Some American financial experts think Bitcoin is just a bubble and the worst investment opportunity. However, Bitcoin's performance over the years has been quite surprising, as it even grew by 9% in 2012. So what the future holds for Bitcoin can only be observed further.
