> I have heard they lost over $4 billion from the Luna / UST crash

Source for this? I can't seem to find this claim anywhere.

No public source but number seems approximately correct +/- 1bn. Their 2021 pnl was over 10bn though so they still up massively.

Half the traders I know who were sitting on 3000% gains in 2021 are down to 300-500% gains by 2022.

Crypto markets fall apart as quickly as they go up. Most who entered the market in late 2021 are down and will be down for years (forever if they're holding some dead altcoin).

You are referring to mark to market gains/losses and not actually realized, correct? Like jump didn’t actually clear 10 bill in profit or lose 4. They were in early size and let it ride but actually investment was small, do I have it right?

Mark to market and realized losses are the same thing for a trading firm.

I've also heard that 10-man team at Tower made about $3B trading crypto last year. The team leader got a $600M bonus.

What's $10bn less short term cap gains taxes less $4bn?

You don't trade your money. You trade the clients money and take 2% of the assets and 20% of the gains. Notice the customers don't have yachts.

Jump Trading, like most other HFT firms do not take client money. They trade only the owner's personal capital.

Prop trading firms usually trade their own money.

Jump is a prop trading firm so this is just completely wrong, they only trade their own money.

IIUC you don't pay capital gains when you're operating a trading firm, you keep a balance sheet and subtract losses from gains

This is true for some asset classes. I cannot speak to crypto, though.

I work in the industry and know a lot of people and that is what I heard.
