The hash being controlled/dominated by a small group is absolutely related.  I would even bet that this last major issue with the blockchain was directly related.  How soon we forget.  It was like 20-30 days ago. 

The miners have created enough problems.  They have also made more than enough money while wreaking havoc on the stability of this coin.  What's with the pandering to the miners?

So you switch to a different algo. Then after a few weeks or a month, the hash power once again moves to one group, and we see another unintended fork..

How many times does this have to happen before you switch to POS and stop it once and for all?
