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've been a holder for a long time, and have a stash of coins my TREZOR that I don't intend to sell anytime soon.
However, I did begin trading futures on OKCoin after hearing about the platform from other people I talk to, and I made some solid gains going long on leverage for most of the ride up, and trimming my position incrementally as we approached the top. I was entirely out by the time it crashed. My personal goal is just to trade with the aim of increasing my stash as much as possible, while waiting for the eventual big bull cycle up at which point I might finally cash out most of my coins for good. I don't intend to sell any at any price below around $2000-$2500 USD/coin, which I hope should materialize sometime in 2018.
