Idea can be like this:
BCH Community starts a pool on BOINC projects computation with Gridcoin
Community Earned GRC are converted and paid out in BCH
Pool may require some administration
Earnings may not be high although these should include 10 GRC block rewards in addition to the compensation for computing scientific tasks..
Promotion of BCH community
Help to scientific research
This option is also possible to do individually, without community and and a pool. There are 2 options available:
Then GRC can be transfered at no cost and exchanged to BCH on SouthXchange or elsewhere.
Both android app and in-browser mining are technically simple.
However, an advantage of pool can be in earning block rewards and conversion to BCH. As GRC has no convenient wallet with private keys.
Earnings won't be high and these will not be higher vs. GRCpool already available but the point can be if BCH community finds this project interesting and fun to promote BCH.
Freegridco.in has added an option to withdraw in BTC, DOGE, LTC, DASH but not BCH!
