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?

People or company they are holding lots of bitcoins where they will sell it when the price is very to dump it and make a big profit when the price decrease they will start buying again and holding its like investing their money on bitcoin by holding them in long term.
