Check for accuracy: $1.8 billion = $1,8 мільярда (Ukrainian uses comma as decimal separator? Actually in Ukrainian numbers, decimal separator is comma, thousands separator is space. But here $1.8 billion is English style. In Ukrainian, we write "1,8 мільярда доларів" with comma for decimal. However, the original uses "$1.8 billion" so we can keep "$1,8 мільярда" but note that dollar sign and number: in Ukrainian text, often "$1,8 млрд" or "$1.8 billion" may be left as is. To be safe, I'll use Ukrainian format: "$1,8 мільярда". Similarly for "$62,000" - in Ukrainian it would be "$62 000" (space) or "$62,000" as English? Better to use "$62 000" but keep comma? Actually original has comma as thousands separator. In Ukrainian, thousands separator is space, so "$62 000". But to avoid confusion, I'll keep the original English number formatting for currency amounts as they are universally recognized. However, requirement says "Keep all facts, numbers, and data accurate" - but doesn't specify locale. I think it's fine to keep as "$62,000" and "$1.8 billion" but translate the text around it. But note that in Ukrainian, decimal is comma, so "$1.8 billion" would be "$1,8 млрд". I'll adapt: use "$62,000" (thousands comma) and "$1,8 мільярда" for billions. But consistency: in the article there is also "2% or 3% dip" - keep as "2-3%". Also "50x leverage" -> "
