I sent Bitcoin transactions two days ago, nearly 48 hours ago. So far they still show as "Unconfirmed transaction". I set the fee as 8 satoshis per byte, with the total cost to be 0.0000081 BTC. According to this site
https://bitcoinfees.earn.com it should take between 25 mins to 480 minutes (8 hours) to be confirmed at 8 satoshis per byte. From their graph there's 2,433 transactions in the last 24 hours with that same fee. What to do and why hasn't it been confirmed yet?
maybe you have to be patient to wait, I know bitcoin is probably currently busy like a crowded vehicle everywhere or maybe now there are improvements so think positively and stay calm
