Its like any bitmain news causes mass hysteria on here now. A miner that is only being sold in China for a coin most people know nothing about and people are already talking shit about ROI and not buying the coin. Their announcement from a year ago says very clearly: "POW Algorithm that is friendly to AI ASIC chips." They are actually trying to make standard ASICs obsolete and instead use hardware designed for machine learning.
The thing is, though, that the B3 is not being only sold in China as the entire email they sent to me was in English and the link to the Bitmain shop in the email lead to the English site. Bitmain's development of Sophon most likely also helped them develop the B3 as its PoW algo is based off of tensor computing. Part of the hype surrounding the B3 miners is probably attributed to the fact that the algo this coin uses is different from any algo Bitmain's developed.
An estimation of ROI can be important if you're trying to decide whether or not to buy the B3 and it should be if you're buying any miner at all. It's natural in any miner announcement thread that people ask about ROI time. Investing in the coins is fine, but this thread isn't primarily about speculation in prices or buying coins.
I get that, but this thread is already full of "fak bitmain" comments. The fact is the mainnet just went live today, almost everyone is having trouble connecting to it. So who knows what the hashrate or difficulty will be. Block time: 150 seconds (2.5 minutes), Block reward: 412.5 BTM Mined coins will represent 33% of the sum of all coins and reward halves every 4 years. If you do the math, that's 237,600 coins a day. For simplicity sake lets just say that 10,000 of these bitmain miners make up the whole network, that's $24 a day. There has been a testnet running this whole time though, so I'm sure the people who have cared enough to participate have a good understanding of the value (or lack of) of this miner. One thing is for sure if you want to mine this coin, you either pay Bitmain a few thousand dollars, or you can spend 10x that much on an Nvidia Deep Learning machine. This coin will not be mined by the average joe. And this is one of those situations where it pays (literally) to keep up to date on everything crypto.
I agree that if someone is considering buying a miner that they should have all of the facts. It just gets old that there is a subset that act like the sky is falling every time an asic is announced, especially when its for a coin they weren't even mining to begin with!
Also, one more thing. We have to take OP's post with a grain of salt. How does he know how many were produced and what the price is. The email states: "Correct price will appear after the scheduled time of launch."
