This is called falling off a cliff . ARN just got delisted from Binance , though technically it happens on the 20th of July . But you can clearly see the whole chart looks like it's taking a hard dive down ! Don't touch this . In case you didn't know then let me tell you - "Never put all your eggs in one basket " . That way if one of your holdings tanked like this you would still be OK with your other coins ( and no , I'm not holding ARN . ) DIversify your holdings and your trading strategy . Have a plan ! Be cautious too . One safe strategy is to go where the volume is ... and also start trading some of those coins that appear to be "not as joined" to Btc swings , in other words , coins that have their own traders that favor that project.
