Hello, I used to do transactions with 25 sat/byte and it would be confirmed in 10 minutes at max. Now I use 60 sat/byte and it takes hours to confirm, did the miners raise their fees for confirming transactions ?
No, blocks are getting filled to the brim, not a sign of them raising their criteria for fee. The problem is the huge influx of transactions that pays a higher or equal fee than you. You can try to use bitcoinfees.21.co as a estimate for TX fee.
Shouldn't fees be a bit lower now that Bitcoin is more expensive ?
No, they can choose not to do that. If they did set a limit, they would likely have no effect on the confirmation times unless its a collective effort by many big miners. But anyway, pools usually don't regulate them unless there is a need (eg. Huge and obvious spam attacks).
