I am new on Bittrex site. Can someone explain to me how the value of a coin that is rising fast over $1,000 in less than 1 hour (BCC) and has large amount of sellers and buyers all of the sudden the screen flashes and in the next second the price has dropped over $700 in 1 second and now all the sellers that were pushing up prices are all in a selling mood with prices dropping fast. How does that happen so fast. I have watched it happen several times. When it happens all of sudden the hot market seems to disappear instantly.
