This is how you get rekt holding such shitcoins. #delisted from Polo.
Isn't it logical that it gets delisted? Volume is just not big enough. And more exchanges coin has, harder it is to maintain high volume on all exchanges. If you want to help then trade this coin.
According to current situation:
https://coinmarketcap.com/currencies/bitcrystals/#markets and if there is no fake volume it is better that it gets delisted from Polo instead of Bittrex or Zaif. I think one good exchange is good enough for coin like BCY.
I wonder if i buy BCY and hold, when the price corrects will the price for the blockchain cards decrease in terms of BCY? For example I need now with current prices more BCY to buy a card, but if price corrects will I need less BCY to buy cards?
It is same rule for cards as for any other crypto currency - supply and demand. What exactly do you mean by "price corrects"? If you think of price decrease then it would be more logical that one card cost more BCY, since you pay less $ for same amount of BCY.
