Related to #1489
Russia has been added to PayPal merchant country list but the Russian Ruble currency has not been added:

magento2/app/code/Magento/Paypal/Model/Config.php

Lines 196 to 217 in 0be91a5

	protected $_supportedCurrencyCodes = [
	'AUD',
	'CAD',
	'CZK',
	'DKK',
	'EUR',
	'HKD',
	'HUF',
	'ILS',
	'JPY',
	'MXN',
	'NOK',
	'NZD',
	'PLN',
	'GBP',
	'SGD',
	'SEK',
	'CHF',
	'USD',
	'TWD',
	'THB',
	];

The PayPal currency list used by Magento is outdated and the same problem would be with another currencies.
Please use the official PayPal currency list: https://developer.paypal.com/docs/classic/api/currency_codes/
Please note that "For in-border payments (payments made within Russia), the Russian Ruble is the only accepted currency. If you use another currency for in-border payments, the transaction will fail returning error code 10001 – Internal Error."
