Yep. The broker is effectively buying at $19.80 and still selling to their customer at $20.00. Now, crypto is actually innovative in just how easy this is to do. In fact it’s almost required since the transactions are processed in bulk and the miners get to decide what order all the transactions in that block go in. The public mempool also means that even if the miners aren’t doing it themselves anyone who wants to front-run basically has a whole conga line of good-faith users (suckers) to get set in front of and identify the most profitable position. Without the miner’s privilege you’ll need to deal with transaction fees and it’s going to be harder to find opportunities, but it’s so easy to search that I wouldn’t expect it to matter.
The worst part is that I don’t even disapprove of the project of putting people in space and keeping them alive and making more of the universe permanently habitable/inhabited. But the insistence that at present it should be an immediate priority rather than acknowledging that it’s a curiosity or a challenging test to expand our collective engineering and scientific abilities in ways that can have direct benefits elsewhere is just delusional. Like, the problem is not that we need to go to space now because there are incredible economic opportunities we’re leaving on the table. We should be funding it more just like the rest of basic research, not trying to grift the necessary funds out of a billionaire class who would rather literally light their money on fire than pay it into a democratic government.
