You can subscribe using cryptocurrency in anonymity. All you need is an email and a password to log in. You will not be asked for a billing address or a name. You also need a Crypto-exchange that handles Ethereum (ETH). Subscriptions are pre-paid, as it goes against the system of cryptocurrency to allow automatically recurring payments. Instead, you pay for how many months you would like in advance.
If you are new to cryptocurrency, I recommend using a user-friendly exchange like MetaMask or Binance. You can buy cryptocurrency there using your bank card.
My pre-paid subscriptions are also paid into a MetaMask wallet and there is a widget for it at checkout.
Binance works alot like MetaMask but is more meant for crypto trading than for doing purchases online. However, Binance is available in many countries where MetaMask is not. This often coincides with other payment methods like VISA, MasterCard, Paypal, and so on, not being available in those countries.
You can buy Ethereum (ETH) with your bank card on Binance (including in Russia) and use the Manual Transaction form during checkout.
Given the current “situation”, this is your only way to support or pay people outside of Russia and the select few countries that still allow monetary traffic between them and Russia.
