$Cardano (ADA.CC)$ this is not stock bussiness . It a coin's value . Why are those sellers want to short at every level of the values when there are a lot who wanted to buy it to make the coin value goes higher . Why cant the seller's wait for it to shoot rocket high up to the value of ETH and then BTC , then get the big profit. Are they stupid or troubles makers who think this is a stock market item.
