As for exchanges, Cryptopia, Lykke, Coin Exchange, Evercoin, Coinlink Korea are already signed. Bittrex and Hitbtc are now in the process of negotiations.
Are the tokens locked until the end of ICO? Is it possible to trade them before official listing on Cryptopia, Lykke, Coin Exchange, Evercoin and Coinlink Korea?
Of course, you cant trade until the end of ICO. By the way, now there are some talks that it would be nice to correct the PKT price in connection with rising Eth. As for me, it would be disrespectful to the early investors.
