If you need more decimal places e.g. 8 for Bitcoin ( 0.00000001 BTC) – please add this code to your Child Theme functions.php file (read more about child themes here).

add_filter('vehica/price/decimalPlaces', function () {
return 8;
});

If you need only 3 decimal places (e.g. 0.001 ETH) please use this code:

add_filter('vehica/price/decimalPlaces', function () {
return 3;
});
