Now the priority is 19170/63139... My guess is it will take more 10 days to confirm
That (
63,139) was exactly the number of transaction in their node's mempool and your transaction was at the 19,170 from the bottom.
You'll have to wait for the 43,969 transactions to get confirmed before yours can have its chance (
or vice versa?) I dunno which blockexplorer was that.
For the record, this month's average total confirmed transactions per day is 350k-400k txs.
Yours won't take weeks, just days if the mempool doesn't get worse.
