Ah, ok. That makes more sense. In that case, hopefully we can make a good profit before they flood the market with them.

I think I ordered from the first batch (though it hasn't been despatched yet).

I did receive an email today about a partial refund however. Did you receive one of these too?

Quote:
Thank you very much for your support towards Bitmain and our products.

This email is to inform you that we will provide compensation for the orders of our B3 miners that were purchased earlier at a higher price than the present batch.

Relevant orders:


Those who have purchased and fully paid for our B3 miner at the price of USD 2453 on our website (https://shop.bitmain.com/)

Compensation method:


Those who have purchased and fully paid for the B3 miner at the price of USD 2453 will be refunded the equivalent amount of USD578 in BCH (Bitcoin cash),

The exchange rate will be the real time exchange rate when the refund is credited into your account in around 1-2 months after the refund request is received by us.

Post Cloud Mining

Hi to everyone. Quite an interesting question here. What would you prefer: mine with Asic some Dash or Bitcoin, or use cloud mining with the same coin? BUT, provided that with cloud mining you have a 25% discount? I mean I would definitely avoid cloud mining and such a high discount makes me even more suspicious. Still, it might be true. this is the code I am talking about (http://hashflarecode.com/)
So, what do you think? Scam or not?

Call me old fashioned if you will but I prefer something I can hold in hand instead of long term contract with some company I do not know half way around world and pay for whole term upfront. They may be perfectly legit with good intentions but you do not know what will happen half year later, they may go bust or their government may force them to shut or move premises to another country increasing maintenance costs. I cannot remember which one it was but I remember one it was but there was one where maintenance costs in creases more than 3x as they moved, later were halved but still a lot more than at the beginning of contract. I would rather just buy the crypto and hold. Or if you want to invest in new emerging coins it might be an idea to buy some short term hashing power from NiceHash or MiningRigRentals but not cost effective for established coins.

Default Antminer B3

Received B3 on Tuesday, it's surprisingly loud for 360W machine, louder than L3+ and I think even D3, somewhere between D3 and S9. Fans seem to run at constant speed, temps very low, around 30C board, 40C chips. Web interface does not show fan speed. Also small number of chips only 12 not 100+ like on other Antminers. Good news are that it does not care about fans being connected and keeps running with exhaust fan disconnected, this brings noise level down comparable to L3+ and does not increase temps. I think I will replace the fans with pair of these and should be enough cooling and low noise to keep in house https://www.amazon.co.uk/gp/product/...KL5A1OLE&psc=1 if I decide to keep it long term. As it is running cool I was looking to see if it can be overclocked. There is a hidden 'Advanced settings' page http://IP_Adress/cgi-bin/minerAdvanced.cgi by the looks of it is autotune frequency like later models of S9. Apparently some people changing firmwares and using hidden page have overclocked their autotune S9s some even running 19TH/s+ with submerged cooling, but it did not seem to have any effect on B3.

As far as the profitability goes at launch it would have made 200+ BTM/day at a price over $1, at the moment it's a bit over 20 BTM @ $0.62 with about 0.1/day running costs, no section for them on MRR yet. So while not great it is still well above likes of S9 or L3+ especially when you take power costs in account.

Interesting fact also that Bitmains 1st gen AI chips turned out to be bust with sub par performance with them promising that 2nd gen will be on par with nVidia. That makes me wonder if they just found another use for their 1st gen AI chips in B3 and if nVidia chips could be used to mine Tensority algorithm with increased performance and if there is another more efficient Tensority miner with gen2 chips from Bitmain just around the corner. With B3 prices on e-bay being 2.5k+ I might try to sell ours and take a bit of profit as it only cost us 1227 all in including delivery and taxes at the BTC prices on the day of purchase and then maybe just buy some BTM with the profits from sale as the it is interesting and shows some promise with the backing Bitmain.

On the GPU front it's been doing rather well with them pulling the weight lately as ASICS does not earn much more than electricity costs although I do belive there is a lot to give in future from LTC and ETH, not so sure about BTC.

Done very well with RX480/580 cards on CryptoNote-Heavy algorithm, had some 10 day contracts that netted 4/day/card. Even switched 1080Tis to CN-Heavy for a while but only did one rental as the prices dropped. If you are top of the game and follow new trends there are more money to be made but takes a lot of time as the new more profitable coins/ algorithms does not appear on calculators straight away if ever so you need to find it yourself with a lot of searching.

The first boost for CN-Heavy was from Haven about 3/card/day, then dropped to 2, then Loki brought it over 4. It has dropped now but still 2+ /day/card so still doing well.

Also ventured a bit in PHI1612 with 1080Ti on MRR mining LUX when not rented for a while then x16r mining RVN when not rented but x16r is very heavy on GPU with high power consumption and high fan speeds so as the prices dropped I switched back to Equihash. In the process I have expanded my portfolio now owning small amounts of LUX, RVN & HAV.

RX card prices have dropped with 580 around 250 and Vega 56 450 so might be good time to buy. nVidia cars still a bit pricey with 1080Ti 600+
