The vast majority of BOINC users crunch without receiving any rewards (gridcoin/other), it's only a small minority of BOINC users (team Gridcoin) that have begun earning rewards.

I remember thinking the same about Bitcoin when you were able to mine Bitcoin with weak CPUs. Who knows where Gridcoin will be in 10 years time.. BOINC will likely still be around, It's been around for over ten years already.

If we manage to work out how to remove the need for the mandatory team requirement, the distribution of gridcoin may increase from 2k users to tens or hundreds of thousands of users. There is no coin cap though.
