Yes, bitcoin can go up much higher than the current price. Now the price had been moving downwards and now it had reached around $5700. Things happen unexpected and now this can be used as an opportunity to invest into different altcoins which are on the potentially growing track.
yes it's true that price is going down and in the future may be some unexpected things happen and then after some time the prices will go up and become the most high currency in the world. bitcoin still go up and that will be the good time for those who invest in these days and wait for the right time. i like to invest but i have not enough fund to invest in this valuable currency.
