2 friends of mine did an entire presentation on their deep dive into crypto. They started a long time ago, and very smartly: Instead of trading it themselves, they wrote bots to play the arbitrage game: Find price differences between 2 markets for the same product.
They made money with it. More and more, spending significant amounts on hosters to run their bots more often and on more markets.
It was an interesting presentation even if only for the technical details on how they implemented it all.
It took one whole hour. Somewhere near the end, about 5 seconds was spent on 'anyway I lost it all due to the fall of FTX', and then another 5 minutes on how they want to get back into it and what they're looking at, because an individual can no longer play the arbitrage game today.
I had to ask some fairly blunt questions to disillusion the audience. At the end of all that, and with all that effort, *they lost quite a bit of money in the endeavour*. And they wanted to get back into it.
What. the. heck.
