- Amount at risk
$10,000.00 × 1% = $100.00 - Point value per lot
1 × 1 = 1 USD - Position size
$100.00 ÷ (500.0 points × $1.00) = 0.2000 lots - Rounded down to your lot step
0.20 lots - Amount at risk at this size
0.20 lots × $500.00 = $100.00 - Position value and effective leverage
0.20 lots × 1 × 81,758.00 = 16,351.60 USD; ÷ $10,000.00 = 1:1.6

What to know about Bitcoin (BTC/USD)
One lot of BTC/USD is one bitcoin at most CFD brokers, so every $1 move is worth $1 per lot. calc.forex treats a $1 move as one point. EU and UK retail clients are limited to 2:1 leverage on crypto CFDs, so margin requirements are high.
Bitcoin trades around the clock at many brokers, including weekends, which forex pairs do not.
