We Accept Bitcoins

For those users who can't or don't want to use Paypal or just want to be cool we added an option to pay with bitcoin (BTC) and litecoin (LTC). This service is implemented by payment gateway CoinPayments.net. You can make a subscription or buy PDF book for cryptocurrency. The amount is automatically converted from USD value according to current stock value.
