I had a small amount on Bittrex. 0.173xxxx of it. To be exact.
I just sold it now. Was suprised to see the price rise initially. Dropping now. Not convinced it will retain enough support long term. If (as is suspected thus far) they're only getting < 5% of the hashing power pre-fork, then the $300 it's trading for is probably a bit high.
Can't transfer in our out. Could only trade what I had on there. So I dumped it a couple of $'s below the $300 mark. What the hell. It's a free $50 of BTC now!
Remainder is in cold wallet. Not going to bother transferring the keys for that just yet. I only hold about 3 BTC. But do wonder if it would be worth just taking the $900 now and being happy with it. Long term, with the support it seems to be getting, I suspect it will struggle to stay over $100 ...
