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 sold all my bitcoins at $860 and after one week the price was $1133.
More regrets than profits for me.
Only the big whales can make big money.Do we know any major bitcoin players who are Bitcointalk members?
We have a lot here. Those that are pretty silent are the ones who've got most. Don't worry, it's gonna have a lot more spikes like that in the future, plenty of opportunities to come still.
