// Scale is the number of decimal places in the currency (e.g. 2 for USD, 8 for BTC). Max is 14.
MoneyConfig::configure(
    new Currencies([
        ['name' => 'US Dollar', 'symbol' => 'USD', 'scale' => 2],
        ['name' => 'Euro', 'symbol' => 'EUR', 'scale' => 4],
        ['name' => 'MyCoin', 'symbol' => 'MC', 'scale' => 8],
   ]

$tenBtc = new Money(10.50, 'BTC'); // throws \Laxity7\Money\Exceptions\UnacceptableCurrencyException
