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 $1000 anytime soon. Any profits or regrets here? 
There are many big whales who made big money from bitcoin increase. They could get 50% - 100% profits if they bought and held bitcoins from August or September in 2016. I believe that Bitcoin will continue to hit 1,500$ in this year. Just only buy and hold bitcoins when the price is down deeply.
