Japanese beta users called this a reverse Tinder, because you chat first and then get the chance to "swipe" (not a real Tinder swipe, but by selecting "Talk more" or "No thanks"). You're matched with another user for a 10 minute chat, and once the 10 minutes is up you get the chance to choose to match with that person or block them. There's definitely a lot of services calling themselves the "anti-Tinder" these days, but we're not trying to be "anti" anything-- just giving users a chance to chat first to see if they click with someone before deciding whether or continue talking with (or eventually meet) them or not! Thanks for your feedback, we need to work on making our headline more clear!
Probably you'd enter your handle on the site and get a token back which you would have to paste in your profile. Upon scraping your profile, you would then be authenticated and could start receiving tips.
The hard part is getting it to work with umpteen exchanges and wallet systems. Although you could just use Flattr I guess (they support Bitcoin).
