> Since the transaction amount is just a 64-bit value, the transaction fees are the same whether you're transferring $1 or $1M. In the latter case, it will be far cheaper than existing payment processors and banking settlement systems.

Large transactions in the US are done via wire transfers ($10-$20 charge against the account, offset via interest on balances of the cash management accounts) or via ACH transactions which cost about $0.25 also offset via interest on the balances of cash management accounts.

No one is running transactions that exceed several thousand dollars via credit card settlement networks.

You're being downvoted, but its true - many CC and Debit card services have built in stop gaps that restrict the maximum transaction amounts, usually around $2,000. (You can temporarily remove these with a quick phone call)

What cards are those? I've made purchases significantly larger than $2K on several different Visa and American Express cards with no phone call necessary.
