The transaction fee was 54.835sat/B. At the time the mempool was going stupid, things have calmed down a bit now but it's just never confirmed.
How would I know if it has been dropped from the mempool, or might still go through? I've heard that transactions drop out of the mempool after 72 hrs or so. Would it just reappear on my dream account?
you simply wont see the transaction anymore if its dropped out of the mempool.
transaction can be in limbo waiting for a confirm much longer than just 72 hours.
