Needed features for IRAN
Hi from Iran
As an Iranian, I can confirm Stealth protocol is one of the rare protocols that is still working, many Iranians are willing to pay for the premium and Gift the premium version to the ones who can't afford it so that these features will be helpful:
1)Crypto payment (it's critical!)
2)Promo codes especially for people in Iran
3)Add an option to buy the premium subscription and send it to another account as an gift
Thank you for standing with us ;)

3) is also accommodated, you can buy a Proton gift card from the website and send it to somebody else, and that person will get free credit.
Bitcoin payment is not the best fee-friendly method, specially with the crypto exchanges in Iran. I'd suggest you either allow more coins, or accept payments through Bitpay which enables customers to pay Bitcoin with other major coins in their wallet.
As Amir G said, the requirement to login when the Iranian users can't reach the Proton website is a major impediment. They need another vpn to set up Proton VPN.
BTC payment is already available in your Proton Dashboard -> Add credit. You can add as low as $5 to your account.

4) an Emergency Connection way for the First login!
People can't log in to their Accounts if they don't have a VPN already
