Bitcoin itself have "0" value.
But all its about proper advertising, fud, interest and marketing takes BTC price to skyrocket. If people continues to remove their interest, faith and trust from BTC then is sure one day BTC will really come back to its original value of "0".
I see some group of people with higher equity can be easily take control over market and manipulate it. But in such scenario many small players get kicked out of market. Even many lost their equity by nearly 70%.
