You might can have that opinion about CureCoin.

But folding as such was never made for profitability. It is per concept a volunteering distributed computing project to increase our knowledge about the "misbehavior" of proteins. Folding existed before CureCoin for many years with an amazing contribution from a number of great folding teams. With individuals reaching 2bn points or making 10mPPD, each day: for free ! for us !

We should not make the mistake and focusing only on profit. There might be other opportunities.
Folding is different.
