yes that is bitcoin, it is difficult to follow it will not go out. Bitcoin will always be stronger in every year. The wheels keep spinning, just waiting for bitcoin to be back again and give a lot of strength to all its users.
nothing can provide certainty that will occur in the future regarding bitcoin. stay 2 months towards the end of 2018 keep holding the coins you have. if the price stays the same I will trade and leave a long-term investment.
