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.
Bitcoin is not even close to reaching its limits, many people think that the current price is simply too high but I disagree the price can go up especially if you are willing to hold for a very long time, I know that holding for a long time it is difficult but we must do it if we want to get the most profits out of bitcoin.
Trading follow the cycle of Bitcoin, you will not need to spend much time to wait the price of Bitcoin increases and take profits. To be honest, only holding Bitcoin and wait the price of Bitcoin reaches your target without any signal, reason or momentum growth will make you lose money.
That is not true if you are a true holder, Im willing to hold for many years so anyone that buys today no matter the price at which they do and hold for several years is going to make money, we only need to look at the charts to know that is the truth.
