Mempool will likely be less congested tomorrow. Wait till tomorrow (Sunday), the mempool will be less congested, and likely the transaction will be confirmed.
I'm not so sure. I know things usually get better on Sundays, but I don't think we will see the mempool empty down as low as 70 sats/vbyte over this weekend. Hashrate has dropped acutely over the last few days, and we are currently lagging almost 70 blocks behind the 10 minute average for this difficulty epoch. We've only mined a single block in the last 2 hours. Combine this with the price pushing ATHs and the increased transaction volume that this always brings, the mempool is currently filling up more rather than emptying. A few hours ago 70 sats/vbyte was 20 MB from the tip. Now it is 30 MB and climbing.If the hashrate doesn't pick back up and we continue to find blocks ~20% slower than predicted until the next difficulty readjustment, it could take weeks for us to clear down to 70 sats/vbyte.
I do not think I have seen such congestion in mempool before.
Last time it was this bad was around the $20k ATH at the end of 2017.
