Just a couple of weeks ago bitcoin was blasting over $1000, so I am wondering if anyone made big money by selling their BTC? Now it has came down to $830, even if last week it was close to $900, so I am not seeing getting back to $1000 anytime soon. Any profits or regrets here? 
I convert my bitcoin at $800+ then I regret because the price pumps at $1000+, I never thought the price will increase in that price. So now I am ready to buy at dump price. May I know if what price is the best to buy bitcoin? So that If the price of this coin will pump, I can gain more profit.
