Bitcoin (and the other coin systems) ultimately need to be able to handle transactions by a large number of users if they are to gain widespread acceptance. If I want to buy something with my coins, I don't expect to see "Sorry your transaction timed out. Please try again in a few moments". That is NOT confidence inspiring to me as the coin holder, and certainly not to the person/business expecting to receive my coins. Bitcoin needs to be able to handle at least a few hundred transactions per second as a first goal.

Bitcoiners don't actually want people spending Bitcoin. The entire Bitcoin narrative has become buy and never sell (HODL). The more friction around transacting with your coins (other than buying) the better it is for the asset value.

Transactions can't time out and there are two main solutions for businesses that want to accept bitcoin: * Accept transactions that are in the mempool * Use the lightning network Accepting mempool transactions obviously has lesser guarantees and unfortunately lightning hasn't seen great adoption even from centralised exchanges.

  transactions that are not chosen for inclusion in a block (likely due to low transaction fees) do age out of the mempool eventually, so there is a network-enforced "timeout". It's not a hard number but it will eventually happen. Also obviously there is a human-imposed "timeout" too. Like, if you buy something with Bitpay they expect your transaction to be included in one of the next 3 blocks. If it's not, they will "timeout" the transaction and it bounces. If it is eventually mined for inclusion, they will voluntarily return it to you minus whatever fees they choose to charge (average transaction fee is $24 right now, so you will lose $24 sending it to them, then $24 for them sending it back to you, and $24 to send it again). https://ycharts.com/indicators/bitcoin_average_transaction_fee https://ycharts.com/indicators/bitcoin_average_transaction_f... (of course they don't have to send it back to you, there is no network-enforced mechanism for this, they could bounce the transaction and then if it gets included an hour later they could not pay you back, the money is under their control once you've signed the transaction. They could even maintain a separate mempool of these "dead" transactions and use a friendly mining pool to process those transactions preferentially...)

When this becomes an actual problem (it isn’t yet), the lightning network is ready to handle that kind of throughout.
