In my opinion bitcoin will raise only next year so this is a good time for bying it while the price is low
It will definitely rise in 2019 but there is a possibility that Bitcoin can grow in December. I guess, we have to use these days to invest in BTC as soon as later, this crypto will be expensive again.
Most of us are still expecting a one last pump this year and it will only be possible in December as this month is full of dump.
Anything could happen, crypto is so unpredictable and most of us are already losing a lot by panic selling, time for the whales to manipulate the price going up.
