What I mean was how long will bitcoin keep going up in price of USD which is United States Dollars. I was wondering since it seems to be going up like the stock market once was. When something is going good, there is always a bad side to it
For how long, as long as demand is present and bitcoin was being used in any ways, the price movement will continue to move and will have a USD or any fiat value. Bitcoin will really look as a currency that will continously to gained more value in the future because we have lots reasons to believe that it will happen. Actually we are living the proof of it now.
And of course unusual thing can happen on the way as there is risk always. Take care of the risk and you will be fine later.
