+### 💡 Dynamically add currencies
+
+Class currencies are elegant, but not necessary. If your currency specs come from the database, or some API, you can register them as arrays.
+
+```php
+// LoadCurrencies middleware
+
+currencies()->add(cache()->remember('currencies', 3600, function () {
+    return UserCurrencies::where('user_id', auth()->id())->get()->toArray();
+});
+```
+
+Where the DB call returns an array of array currencies following the [format mentioned above](#creating-a-currency).
