I'm thinking about the bot and the dumpings. You can check on Bittrex that "sell volume" is way more than "buy volume" in the past week. Someone or a few people sold their coins but bought way fewer coins. Where do the coins come? First, I thought they bought the coins in the past. But how much? I guess, some of the buy orders are their and they sell mostly to their buy orders, then they sell the bought coins again to their buy orders for a lower price to ruin the price. I don't know the benefit of it and it's just a guess. To nullify this operation, we should put more buy orders to acquire their coins.
By the way, I just checked KTK on Coin-Swap:
https://coin-swap.net/market/KTK/BTCJust look at the buy and sell orders. All of them are one digit and two digits except two of them, which are 100 KTK and 149 KTK. They are all the bot's orders.
