While classing CureCoin (and FoldingCoin and to a much lesser degree GridCoin) as "legal bribes" is technically correct, the term "bribe" has enough negative associations that it's REALLY A BAD IDEA to talk about them that way...
I think that you, like many others, are missing the central, fundamental point that
it's not merely payment for being part of the larger project.
CureCoin is a payment for forgoing all other team choices and folding on team 224497, and on team 224497
only. I'm glad the term has "negative associations" because "it's REALLY A BAD IDEA to" pay people to be on team 224497
only.
Which synonym for "bribe" has enough "positive associations" for me to use in it's stead, so's to not offend your delicate sensibilities?
Allowing any account to earn CURE was a consideration early on in the project. FLDC gets you halfway there - you could earn FLDC while folding for any team; however you still have to create a new username to do it. CureCoin allowed you to keep your legacy name (probably a key reason why PS3EdOlkkola folds for the Curecoin Team, but does not want to interrupt his record, or legacy).
To complicate things, multiple users can fold for multiple teams using the same username but different passkeys (and Curecoin has no visibility into member's secret passkeys). It would require a secondary layer of management to track which username folds for Curecoin, and which does not (see username jim.gluftsis as an example).
from Bruce on FoldingForum.org:
'In the early days, there was no requirement that the username be unique. You might find several people contributing points to the same account if you used a common account name, like "John".'Another argument against allowing anyone from any team to earn CURE were concerns by the larger folding community; many expressing concern it would be unfair to have mixed teams (where some are folding for CURE, and others folding on a purely philanthropic basis - with zero interest in ever being compensated). It could curtail the sense of competition in Chimp Challenges and equipment give-away promos designed to spur participation on other teams. Ironically, some of the loudest voices critical of Curecoin's concept were coming from the EVGA community back in 2013-2014.
What are your thoughts on the successful Bucks incentive program? Although it's true you can get a discount on an EVGA GPU at full price on EVGA's company website, you could instead cash in some CURE and purchase a GPU for 20% off at MicroCenter, or buy it for Bitcoin on Newegg.
BTW, over 80% of CureCoin's social media outreach using the hashtags #foldingathome and #IAmOneInAMillion refer potential contributors to Folding@home web pages - not Curecoin. Of course we hope when new participants chose a team, they investigate our value proposition in the process.
