Why don't these tech support the oldest trick every financial companies have been doing?

They send a cent and see if the recipient received it or not. If the money went through and is secured, then send the rest. Simply by doing this, you could avoid almost all incidents like these.

I fairly regularly do that. It's easy to get complacent and as the average fee increases it becomes a higher and higher incentive to just send the amount.

Transactions are often slow and expensive.

Each transaction takes minutes to complete, and costs an absurd amount of money.
