Question about transactions added to mempool When bitcoin transactions are made, I know that they are put into the mempool. After certain transactions are added to a block and that block gets verified, what happens to all the other transactions that did not meet that threshold? Do they just get rejected?
Do they just get rejected?


No, they will just wait for another block to be included in.

Note that transactions have a time to live in the mempool of 336 hours (configurable using the maxmempoolexpiry startup option).
