I completely agree, the volatility is good for many reasons, among which is it provides a cheaper way to buy more steem in the low periods. I am only new here but steem like all other alt currencies also closely follows bitcoin, but the larger we become the more valuable the whole project will become. I think steem is fantastic and am enjoying watching the value of steem rise knowing I can't easily sell as it is all powered up and I am in for the long haul!
