Margin Requirement of Bitcoin(BTCUSD) on XM MT5 is calculated as follows:

Lots * Contract Size * Opening Price * Margin Percentage(normally 33%)

In case of hedged positions, 50% of the normal margin will be required.

If you are not sure about calculation(of anything on margin trading), you may open a Demo account of XM MT4 or MT5 and see the numbers there.
