The last year or so I have not seen the delay from BTC to FIAT. Today I wanted to exchange some of the BTC to FIAT and it is not instant any longer. I have a exchange sitting for the last 10 minutes.
what do you mean by "exchange"?
you can buy fiat using crypto balance which is instant (or more precisely depending on the market and parameters of your order)
and then you have withdrawals to your bank account which were never "instant"
so what exactly are you complaining about?
I see the same, normally if you use kraken (just the simple account, dashboard) and you SELL your crypto it is instant (it has been like that the last year) now, everything is delayed, and it can take some time before it is sold.
