Dev a testnet should be just 1 block, not 120. This is a scam, don't mine this.
Now it's a scam? Nobody is forcing you to mine it. Also I'm using the coins I have for bounties partly but I don't see why I should create a coin purely for everyone else's benefit.
Been thinking of it and you might not be a scammer, but who knows. I saw a lot of scam coins and that's the common method of scamming.
Scammer or not, 120 coin dump is a really bad scam.
