I've done research on finding the best staking coins and GrowthCoin has been one of them, with low entry, high staking percentage and the impossibility of inflation driving the coins down to 1 sat, which is a problem with high return POS coins. But it looks like the coin has been practically abandoned recently. I would like to get involved with learning more about under the hood programming and maintaining peers, etc. If you're interested in helping, here is the thread:
