I just sent a Bitcoin Transaction with 1 sat/byte [Update]
About four days ago i sent a BTC Transaction with 1 sat/byte fee and guess what today it arrived.
The transaction took 102 hours and about 20 minutes till confirmed.
As you can see at this graph, 1-5 sat/byte Transactions need about 1 week to confirm.
Friendly reminder for all of you, you can set your transaction lower than the average if you can wait for it to arrive.
TLTR: don't loose money on fees if you have time, you can always pump those fees up later
