bitcoin currently does show signs that it will increase again after some time ago it has declined, but it is not impossible that it will come down again but hopefully that doesn't happen
in my view this is a good time to buy bitcoin and hold it until the end of the year, because it is estimated that the price of bitcoin will return high at the end of the year
September 2018 has half gone but the price is still below $7000, it means that this month is also not too good for bitcoin price. People are talking about the big pump in the price because they have seen such pump in the ending months of the last year, but it will not happen in this year because this year is not good overall besides the worst year for bitcoin is 2018.
