It seems very difficult if bitcoin doesnt become nothing. Number of countries legalize bitcoin is one proof that bitcoin has exchange rate against currency. Bitcoin will continue to invite many investors.
i am agree, people don't want bitcoin drop to nothing and i am sure that bitcoin price will be increase more but of course there will be a correction price before to go up. just make sure to sell when you think you make profit and then if you see the price is down, you can buy again and hold for a while.
