be EXTREMELY careful which exchange you pick to buy this on UNLESS you're looking to buy and cash out before you remove from the exchanges. It will cost you sometimes atleast 20,000 DCN to withdraw from different exchanges...yes you read that correctly!

I suggest either checking first if you're holding long term or just get a quick term profit and bounce otherwise you'll spend a lot of money withdrawing it from certain exchanges.

You can simple trade in short time, instead of whitdrow, so little btc fee, thats it

Good advice @neverxpected ! Although I believe a lot of time these extremely high fees are a byproduct of the coin price going up in a massive surge and the exchange not prioritizing the recaliberation of the withdrawal price to match the real time value.
HitBTC is famous for it, and they did the same to DENT... by the time they finally lowered the fee, DENT had surged again heaps and we were back to the same problem. :p

Sorry didn't answer your question before - Just search for the coin on coinmarketcap.com and then on the coin's profile page click on the "markets" tab next to the "charts" tab and it will show you all the exchanges the coin is listed on to purchase from.

@davidblackwell You can purchase it on CoinExchange.io. Withdrawal fee 1 DCN.
