After halving, we can say some miners have left. What do you think? More miners will leave too? And what if hashrate drop more?
The hash rate is declining but the drop has been fairly modest. Difficulty is still technically slated to increase in 4 days, although it will probably become a modest (1-2%) decrease by then. It may take 2 difficulty adjustments for the fee market to normalize, but I see no cause for concern.
Fees have also been driven up by increased exchange activity recently, which usually coincides with boosts in price.
By the way, I strongly recommend Johoe's mempool viewer over Earn.com. 110-120 satoshis/byte is likely to get next block confirmation at this time despite what Earn.com says.
