I have been observing the coin market cap for few days and there had been dramatic changes. Two days ago Ethereum drops to 20 cents within few seconds but it recovered its position rapidly. Another coin is trying to move ahead which is light coin whose value has been increased by 44% since last week.
Since last week steem value is also dropping and the drop is recorded as 17%. DASH is the only coin who has maintained his position and haven't dropped more than 2%
