Yes, and No.
If you see the recently mined blocks, Flypool usually takes a half of the network hashrate and blocks.
But recently the unspecified pool (I’m guessing that it’s BITMAIN’s private pool) is taking quite a large amount of blocks under the address “t1S4ydQEgzgLuWWvHiRBfcqW7AFE3RssVHy”, Now Flypool barely makes their 50% hashrate.
