I personally chose to keep my coins myself as well, I had considered sending some to Bittrex or HitBTC, I didn't trust hitBTC and in the end decided not to send them to Bittrex but people who did use Bittrex have ahd control of their coins sooner than the rest of us who control our private keys and faster than myself who chose to keep them on a trezor. Personally had I had the opportunity I probably would have sold mine at $1100 and then bought back a day later at like $400 but I'm not hugely concerned over it and I'm not smart enough to figure out how to get them off my trezor at the moment so for the time being I'll leave them be.
Also, I should add having funds frozen was the reason I ddin't trust hitbtc, when I tried to do a little research on them I kept comming across articles that talked about them freezing peoples Bitcoins.
