WTF. Whats a coin swap? Is this legal? You can't just steal my coins... can you?
No one stole any coins, you were essentially left with coins that had no developer. Many coins die out, then if you had them on an exchange they can tell you one of two things. 1) Get them off the exchange. 2) The blockchain is broken, and we are delisting the coin(i.e. you lose everything).
The burn address, of this coin, after the swap was finished, got 54,641,736 coins. That would equal 5,464,173 whistlecoins still unaccounted for. And the final value at bittrex puts those coins worth less than 3.3btc. So you can't be complaining about anything more than 3.3btc. What were you doing all the weeks that the coin had a banner saying it was going to be delisted?
Now if someone had coins held in a wallet, not paying attention, then they were also ready to lose coins. Sorry, but these coins are all experimental coins, nothing is promised or guaranteed. You should watch all the coins you hold. If you had a two month or longer tropical vacation, that less than 3.3btc loss should mean nothing to you. And if you would like to get in this coin, you can still do that, as they are on the yobit exchange. Finally, if you held all those unaccounted coins, I'm sorry for you, I don't think there will be an answer you like.
