Here's my !stats from the #gridcoin IRC channel:
fediverse> your next staked block will get you: 17 GRC (research owed) <fediverse> per day, average: 5.7 GRC <fediverse> (BTC (per day): 0.00005062 / $ (per day): $0.03 / $ (per 30 days): $0.88 / RAC (estimated): 136287.5 / magnitude (estimated): 28.60)
There's NO way that you're going to make $40/month with a 980 crunching BOINC projects, at least not with gridcoin. Gridcoin is $0.50 - $0.75, depending on where you look, and even the best rigs won't make more than 100 a day at best.
Pure PoS cryptocurrencies cannot be mined by suchflex.
Then I was wrong, does suchflex also mine ETH then?
It's pretty easy to set up ETH mining yourself and pocket all the money, but that's probably not the audience this software is intended for (Windows users with access to "free" electricity).
The second part is based on Gridcoin, a cryptocurrency that rewards BOINC computations in a decentralized way. So you do all kind of BOINC projects like SETI@home, Rosetta@home (folding proteins),... and the newly generated coins by inflation get distributed according to research done by each user. Again, the important part is that there is no central authority giving out the coins, but each client queries the Boinc projects individually to find out how much research each user has done and the clients then come to a consensus about this, which is stored in the blockchain and is then the basis for the reward each client gets when staking the next time.
Suchflex is basically just a platform built on top of the Gridcoin platform for these "earn money by doing research" projects and simple cryptocurrency mining on the other hand.
