Bitcoins price is a bit high for 11.5k dollar a piece compared to previous month's 7k dollars. Though we all know that bitcoin has still a lot to grow for the next few months, we still want to buy bitcoins at a way cheaper price. I think now is not a good time to buy bitcoin, wait for its value to decrease some more, below 10k atleast. You'll probably need a lot of patience monitoring bitcoin's price on when it is very low. A red or decreasing trend of bitcoin is also an indicator to buy some.
