If Hiro wanted to be smart and rake in some more cash dollar, then he'd get 4chan and 4channel (hue) verified as a website to receive tips and donations from Brave users.
Not really as per to renew passes or do a slow recharge toward a balance because that would require work and management and everyone knows that if you can make money without having doing work, this is best.
However; getting verified might bring in some surprises with donations and tips, and any money is good money.
If Hiro decided to do Slow Pass Recharge, then I'd actually be surprised, but this would probably not happen because again, this requires balance management, and a new internal script/database and Hiro isn't really known for 4chan innovation, nor is he really known for keeping said things entirely confidential.
So maybe its for the best.
But seriously, want to make ez moneys Hiro? Get your website(s) verified as content creators to get some tips and donations.
