I don't think you did the math. I have been 'day trading' BTC/USD since Oct/2023 at 20:1 margin. I now will move to 500:1 margin. Whether I have $20k or $1k, do the math on buying power.
How successful were you for the last 2 years using the 20:1 Margin before we even talk about that 500:1 which more like a casino thing?
Don't think you are the first trader to play the game to leverages. Yes, you could have higher buying power, but how will your performance be winrate wise?
