You can pay your NapBots subscription via Paddle by using a credit/debit card. You can also pay with crypto using crypto-currencies (BTC, ETH, USDC, LTC, DAI, BCH or even DOGE). Additionally, if you are a NapoleonX veteran and you have NPX tokens you can use them to pay your subscription.
Keep in mind that crypto-currencies transactions can take up to 2 hours to be validated depending on the state of the ETH network.
You should also be aware that it is not possible to change your payment method during a subscription period.
If you have subscribed with a credit card payment and now wish to pay in crypto-currencies (or vice-versa), you can change your payment method at any time, for more information, visit this page.
