This is just an quick update: With the difficulty being so low and BitCoin Cash being currently 129.8% more profitable to mine more and more miners are jumping in. Note: Yes, 129.8% not 29.8% as following statistics from Coin Dance shows.
One of the concerns after the hard fork 20 days ago was that people noticed that one group of miners were in control of 95+% of the hashrate but it seems like this is changing, drastically! Over the last 48 hours the ViaBTC's network hashrate for BitCoin Cash went 22.7 PHs to 508 PHs (22 times multiplier)!
The last 144 blocks shows that the "unknown" miners were only be able to claim 66% of the blocks over the last 7 hours which is making the network more and more decentralized.
