Yeah, I'm that old. I witnessed the births of both
Mary Kay and
Herbalife and I know what's at stake in
Three-card Monte.
I think you might not have understood. From what I gather people here are not super wealthy but just basically good people who love science and want to contribute. These are just alternative ways to fold that can "earn" you curecoins or gridcoins as you fold. These can be converted to cash.
For reasons that probably aren't important here, people will swap US dollars for Gridcoins or Curecoins. If you fold and earn Gridcoins or Curecoins it probably won't make you rich (though it could if they followed the same trajectory as Bitcoin, which is far less likely), but it might help pay your power bill.
You don't have to drink the bitcoin koolaid, only to cash in the coins. Heck, you could even donate them to talkfreethought. IIDB and I guess here used to have us the special link when linking to Amazon to help the site, so...well.
