why my HR is about 2.5 kHs, network HR about 70-80 (!) H/s and still no blocks in a day ?
Got the same problem.
Looks like the majority of recent blocks (around your time of posting or around block
1736975, respectively) was extracted by PoS while a majority of the PoW blocks was mined by
SViDg1EJaW71r5FENejW8522WpEXvRPcDs.
A big PoW miner and coins not staking for some time going online taking the lion's share.
Business as usual.
