Higher than what? Monero transaction fees are averaging lower than credit card transaction fees right now. And can’t you just make that part of the price … ?
Just to be clear:
Mullvad charges $5.79 per month flat.
Obscura charges $8.00 per month flat.
Mullvad allows you to buy only one month with Monero and incentivizes it with a 10% discount.
Obscura makes you buy at least three months minimum if you use Monero.
Why is that so? Surely Mullvad is operating at a loss if you purchase a month at a time since Obscura requires a minimum of $24 per transaction.
