I got a prototype of G1-Mini miner yesterday, and tested it immediately
According to their post in Medium (GRIN ASIC Miner IPOLLO Stepping Up Production to Triple GRIN Network Hashpower Soon | by iPollo | Medium):
Based on this malicious attack, IPOLLO miner promises to step up the production with a total 20K(G/S) hashpower in the remaining time of 2020, to support the GRIN community strengthen the GRIN network.
I expect these mini miners will be ready for public sale soon, to get a substantial increasing of the GRIN network hashpower for security.
It does not seem reasonable that a company that has developed such technology has not invested $ 500 dollars for a normal website, no about about or contact page or any relevant information for the buyers.
I forwarded the website comments to IPOLLO, and hope them improving the website quickly.
