Dec 28, 2020 at 20:52 comment added Dennis Jaheruddin Thanks for the edit, at nearly 2 million USD per hour (against current prices) I now understand why this is not happening much.
Dec 27, 2020 at 2:42 comment added Pieter Wuille @Dennis Jaheruddin There is no concrete number, it depends on the techniques used, and those are mostly not part of Bitcoin itself. As a very extreme example... If I just give you my wallet file, you now have my BTC, and the ability to spend it, without anything happening on chain at all. If an attacker wants to fill all on-chain transactions, they can, by just producing that many on-chain transactions - but they'll have to pay enormous fees to compete with others who want that block space.
Dec 27, 2020 at 2:38 comment added Murch I've updated my answer to address the scenario of an attacker attempting to monopolize blockspace.

Dec 27, 2020 at 0:16 comment added Pieter Wuille May be worthwhile to point out that one on-chain transaction doesn't need to correspond to just one real-world payment.
