Quote from Professional:
There are several traders who made over $300,000,000 last year... do you think they're whining about taxes?
Those guys are fund managers and I bet their funds themselves are are registered off shore.
Taxes make compounding your winnings doubly hard and like paying too much in commissions they kill a lot of positive edges. Risky stuff like selling premium becomes nonsensical if a trader is forced to cough up a third to a half of his profits. It's like the rake at the track or poker table-taxes are a de facto odds reducer.
