Title: Difficulty changes
Post by: fyoung55 on December 19, 2017, 11:02:18 PM
I'm new to BTC mining and the recent difficulty shift has me perplexed.  It looks like they "over-corrected" as blocks are being found at 13.7 min per block (that's 37% slower than expected right?).  Is this what normally happens at the beginning of a difficulty shift?  It also looks like the network hash rate dropped significantly over the past few days as well.  Is that coincidental or part of what happens when difficulty goes up?  Sorry if this is the wrong place for these questions.

What happened is that BCH price spiked and it sucked some network hashrate over to that chain as miners switched to more profitable BCH pools. Seems like it evening out.

Not sure where you are getting your numbers. I see difficulty about right or maybe a little low.

A lot of stuff happens right around the difficulty adjustment so you gotta know whats going on.

Difficulty is adjusted every 2016 blocks. Anything can happen in between those adjustments.

bitcoinwisdom used to be my "go to" website for information. It seems that ever since the BCH hard fork, bitcoinwisdom really doesn't know what's going on.

I personally consider the numbers there to be highly suspect, if not  wrong.
