That is 4,000 of them in a 1MB block. @p{par} So $40,000 total reward to the miner @p{--} about eight times current block reward. @p{par} BUT YOU ARE SECURING TRANSACTIONS WORTH SOMETHING LIKE 2,000 TIMES MORE VALUABLE THAN TODAY'S TRANSACTIONS (estimated average transaction USD value for today's average transaction is about $380). And I GUARANTEE that attackers would have a much easier time pulling off a double-spend of one million-dollar transaction than 1,000 $1,000 transactions. @p{par} The math for "large value transactions will generate enough fees to secure the chain" just doesn't work. @p{brk} The math for "lots of small transactions will generate enough fees to secure the chain" might. @p{par} Also: @p{par} I still haven't heard a coherent argument on why large value transactions are necessarily also high-fee transactions. @p{par} I'd suggest you go research existing high-value-payment networks and see what typical fees are for multi-million dollar transactions. FEDWIRE is running at 6 transactions per second, average transaction value over $6million, with fees per transaction @p{(bf}UNDER ONE DOLLAR.@p{bf)} @p{par} Why? Because if you are giving somebody one million dollars for something, you almost certainly have built up real-world trust, and probably have a longstanding relationship, signed contracts, etc etc. @p{par} If you think Bitcoin is different, please explain the scenario where I send a stranger who I don't trust (so have to rely completely on the blockchain) $1million for something. @p{brk}
