I have BCN at Poloniex too BBB71. The excellent price is another reason I am sad about cryptonote closing. I am trying to work out which exchange to go to now as I would like to be in more than one. I have been making comparisons using this site
http://bitinfocharts.com/markets/ However this only gives you the current buy and sell prices and does not give you the fee structure of each Xchange. The bytecoin webpage stated that one could download a bcn wallet on coinex, however this Xchange is in beta so not sure about that one. Besides the link on bytecoin for the coinex wallet didn't work for me. Would be good to hear from others about different exchanges for bcn. I have been looking at bittrex or mintpal and will take a look at cryptsy. Bter has been recommended from another chat.
You can (and should) download the Bytecoin wallet from the official page.
I don't know what are you talking about here but BCN is only traded at Poloniex and Swaphole at the moment.
Keep in mind that BCN (and it's forks) doesn't use the Bitcoin code base and thus integrating it into an exchange is a lot more work than the usual alt coin.
Just go here :
https://bytecoin.org/download-windows-bundle.phpAnd follow the instructions. There is no GUI and running the software requires at least 4Gb or RAM, so be warned.
And remember : Don't keep your coins on exchanges. Exchanges get hacked, bankrupt, flee, scam, disappear, ...Just go to the exchange trade and return your funds to your own wallet.
