Is there an ANN thread in bitcointalk.org or the official grin forum?
because I feel uneasy of trusting them without any user comments.
Could be a virus chest.
Well I haven't found one, but I think that GrinPro's team is related to Ace miner:
https://bitcointalksearch.org/topic/ann-aceminer-13-fast-grin-mimblewimble-cuckoo-cycle-miner-for-amdnvidia-5097693
Both miners passed my security check, but that doesn't really say much.
Ace is apparently a ripoff of GGM. Grin Pro is from the GGM dev: https://grinpro.io/
Who says that Grin Pro is from GGM dev?
Is there anyone to vouch for this miner?
