Earlier quoted context omitted.
In a millionth of a second? This a rationalization for something that is only being done because it can be done.
When I press the buy and sell button, I want the transaction to happen as quickly as possible. So does everyone else. My millionth of a second is different than yours, and everyone else’s. It is no different than buying or selling anything else. And there is no loss from the additional liquidity, you can easily set a limit at which you want to buy or sell.
Nope, not me. I don't mind if it takes like 20 seconds or so.
