Dear Community Liaison, as people kindly explained you, we don't know what to do with your 20% speed increase of a product that was priced for a delivery 2 months ago (aka, in a 5 times more friendly mining ecosystem).
Think about shipping the MPP as soon as possible and if you want to do something useful that you can actually do, ask them to answer my case, (#449), that with legit questions is still unanswered after a week.
Dear cedivad,
HashFast fully anticipates meeting the stated guaranteed delivery date of Dec 31. Otherwise, refunds will be issued.
500GH is an increase of
25% (not "20%") over the initial 400GH spec. And there may still be additional capacity yet to be unleashed!
HashFast already paid for Batch 1's MPP chips and they are being manufactured at TSMC, the world's most advanced wafer fabrication plant.
You may rest assured Batch 1 customers will receive their extra MPP miniboards as soon as possible.
Am I the only one to find this HF bragging about speed increase insulting to intelligence? @HF_CL: It is totally irrelevant if chip hashes at 300, 500 or 700 GHs. It will mine >50% of it's lifetime returns in the first 2 months or less of it's total mining life. The position of these 2 months on the timescale determine the total value of the product, so the only important thing for all of us about your product is it's shipping date. Correction: other important thing is shipping speed, since it can also mess with a few days of mining. Hashing speed is totally irrelevant, since 25% increase is worthless because it is negatively compensated at least that much when difficulty increases >25% every 11 days. I know there's no way you don't understand these simple facts, so yours "Wov, 550GHs!" makes me really offended. Do you really think you are dealing with idiots?
Then i laughed and moved on.
