Per the report, smaller mining pools have made significant gains this year as unknown miners either drop off or change pools.

Unknown bitcoin miners had reportedly gone from solving 6% of the blocks at the start of last year to 22% by the end of 2018.
However, the report claims that this trend has now reversed, as smaller pools have now solved between 23% and 24% blocks in the past two months, double the percentage reported last year. Diar explains that while such distribution has its advantages, also another trend is manifesting itself:
“While the distribution of hash power is certainly better geared against coordinated attacks, the number of pools continue to dwindle. To date, versus the start of 2018, 40% of the pools have now shut down.”
As Diar wrote a week ago, the average bitcoin transaction fees increased by nearly 200% in April compared to March.
