Even though the value of Steem power-ups this week ($57 million) was corrected compared to last week's value of Steem power-ups ($67 million), I don't think it's something to worry about, even earlier this week the exchange rate of steem actually rose above 27%. Steem Exchange Rate is still stable between $0.45 - $0.65. This shows Steem is a profitable investment. I love to staked steem more to investasi.
