In fact it's not a good use-case for Cryptocurrencies because as it stands today, it takes approximately 10 minutes to resolve a transaction in Bitcoin.

You can explain this problem away with appeals to floating networks that ride on top of bitcoin, eth, like lightning etc...however it's unclear why those would be any better than a lower cost ACH or other debit processing system.

I tire of saying this in response to people who believe that credit and debit cards are "instant" but they're not. They take up to a day or two to process and clear and for money to actually change hands. The only thing that's instant is the check to see if you have the funds to cover the transaction. In this case even BTC's on-chain processing of 10 minutes is pretty darn fast.

As you said, other crypto solutions including Lightning Network, ETH, etc are faster and will be able to scale to orders of magnitude more transactions in the near future.

It's not a transaction though, it's a donation. Time to resolve is nothing here, it's fire and forget.

On top of that ACH or other systems require you to put in real banking information rather than having it be a separate wallet you use to pay.

It allows a more complete separation from payment processors.

Check out IOTA. In theory (and so far in practice) it solves the problems you describe. It does not yet have as solid a theoretical foundation as blockchain currencies, though, so there's higher risk that it turns out to have some flaw that nobody's seen yet.

Or just work out some hack around the existing transaction fee systems.

Nano is perfect for this type of transaction. Quick and free.
