There are a lot of viruses, hackers very active, and if payment will be done for every attack the demand in the tokens will be big.
I think if the payment depends on the attack of course we as anti-virus users have to pay a lot of costs to pay and of course it is very burdensome for us as users, I think maybe the anti-virus Romad is the same as other anti-virus where our users only pay once when we first download it. but if indeed as you say that users have to pay every time there is a hacking attack of course people will think twice about using anti-virus Romad, because obviously it's too expensive.
Very often people are guilty by themselfs that viruses appear on their computers, they download pirated content, open unfamiliar letters, visit banned sites.
I think it's fair if people will pay for antivirus for every hackers attack. It will create demand in the tokens in future if it will be a lot of users of antivirus.
