The April 15th power outage in North China had some far-reaching effects

Decline In Bitcoin Hashrate Causes Miners To Earn $16.7 million In 24 Hours

“As a result of the decline in hash rate, backlog in transaction processing quickly surged, causing a mounting transaction fee. With the high mining fee, Bitcoin miners have earned nearly $16.7 million in just 24 hours.

Wu Blockchain noted in a tweet earlier today:

‘Bitcoin miners’ fees have increased significantly. The fees paid to Bitcoin miners in a single day amounts to $16.76303mln. The core reason is that the power outage and inspection in Northwest China has reduced the 20% hashrate, resulting in a backlog of transactions.’

It appears that as a result of the backlog, some users increased their miner’s fee to speed up their transactions.”
