Paying for a $5 cup of coffee with a debt card takes about 10 seconds and invites about $0.10 in transaction fees. Paying in physical currency is even faster and costs approximately $0.

According to https://bitcoinexchangerate.org/fees, getting a single transaction committed within the next hour costs just under $50.

I've heard plenty of ideas to make the Bitcoin network a little cheaper or a little faster. Occasionally both! I've yet to hear a good theory for how the Bitcoin network can ever get both 500x cheaper and 500x faster.
