That's very nice to see this project . I will join this project . I want to ask if I can buy some BTCDs on the exchange for swap and voting election now?
and How long will the swap finish ? May I leave BTCDs on the exchange or not? Thank you.

Yes you can buy BTCDs on Poloniex exchange and use for the swap and the elections.   And the swap lasts 365 days from yesterday.  But you must move your BTCD from the exchange to the ICO site if you want to participate in elections.

Read my post above with all the numbers that shows how buying BTCD right now gets you something like 60% more KMD, per BTC, spent than the end of the ICO got you.
