Even if bitmain has something new coming, it's not going to affect ROI as much as difficulty increases. With all the new miners coming online in March and later this year, difficulty is going to the moon while BTC price is stagnating. I already see it in my mining. Anyone buying S9s now at $2320 may never break even anymore. Especially if difficulty doubles every 3 months like it did the last 3 months.

I hear you. But I guess a lot of that depends on the electricity cost too. Also posts like yours make me hesitant to buy more s9s, but at the same time people have been saying not to mine for a long time, but the people who have been doing it over the last 5 years have made an absolute killing.

s9 price is unrealistic is what hes saying, I bought six s9 for 1400 each or so in october, delivered in nov
2000 per s9 is a joke , the A3 is a better deal at 900 , ill buy a bunch of those

Are the A3’s profitable, I don’t know much about them or the coin it mines?

People mining for the last 5 years made a killing because difficulty was low and price was low. So they got more bitcoins even though price was low. Now price is high ($10k vs. below $800 back then) and difficulty even higher. The whole premise behind mining is to accumulate more bitcoins as bitcoin pricing was just secondary to mining. But now you get less and less bitcoins everyday and that's going to continue. If you spend $2600 to get an S9 + PSU running, it's going to take a full year to make 0.41 BTC (2 weeks ago it was 0.47). If you spend the $2600 and buy the BTC instead of the miner, you'll have about 0.25 BTC now. If you mine with the S9 it's going to take over 7.4 months as of TODAY. Depending on the difficulty increases, it's going to take even longer than the projected 7.4 months as the calculator assumes no difficulty increases.

An S9 currently generates About $11 per day before power & pool fees. That's not enough to pay the rent in the USA. And if you need cash on a monthly basis to pay the rent, spending $2600 upfront for $11 per day isn't the way to go.

Indeed. But i would buy the miner just for the sake of it. It is a good investment for cash, i believe, if for example you need in the next 3 months a source to take cash for paying the rent.

This is one of the most retarded things i have ever read. The level of stupidity this post shows has no parallel

On topic it is pretty obvious they are dumping their whole stock of S9's. Either a big but in price is coming or a new miner for the same price

Someone gets it. Something is changing in the next few weeks/month at bitmain. No one unloads stock like this for no reason; or better yet to reward their customers. ha!

They would have made a lot more by just holding the coins, instead of buying miners with them  Wink

Bitmain starting dumping their stock in December when they had that 2 week sale of S9s with no limit to the numbers people could buy. I literally put 300 in my basket to see, and I could take it all the way to checkout. That was a big factor in leading to the massive increase in difficulty. There will be a whole batch more coming online in March. Then they introduced all these stupid variants and now all the coupons, and the S9 has been for sale for ages. This increase in difficulty will of course affect their own mining profitability, but as I've said before they make more on selling machines than mining.Competition was coming online, they needed to get a new model on tap by 2018 and they sacrificed difficulty (less mining profit) for hardware profit.

As has been said it's their final effort to dump these machines before a new one comes out probably in the summer (well at least after the voucher are no longer useful). I don't see difficulty ramping up as much from say May onwards to the scale it has. Once the new machines come out, and they need to be a massive improvement, then we will see it fly again (although profitability should step up a notch from where it is now)

If you ask what-to-mine website, this is the most profitable ASIC in the world today.
it can mine only 1 coin - siacoin, traded at a legit exchange like Bittrex.

No doubt this is the reason why it is sold out. Will this ROI continue to be like this however, nobody knows.

*** that thing about gpus being more profitable ***

When I first read that a while back I thought it was insane. But my alt coin rig (4 rx 580s, 8gb)
 is pulling in .00064576 btc a day on nh. That's the equivalent of adding  8 T/Hs capacity to my ASICs. Now I see what you mean. I paid 269 for 2 and 313 for the other 2, so about 1200, and I just frankensteined them onto my existing gaming pc. Compared to a 6.5 or 9 T ASIC that's far cheaper and more profitable.

I don't think what you said is so crazy anymore.

GPU mining isnt THAT profitable, i built a rig 10 days ago 152 th/s 6 rx580 etc etc 3100$ 200 shipping to my country 3300 im making 360$/month with a coupon i could get an s9 here for a lot less than that and making 400$ a month

And all that is me buying the video cards by myself wich i know most ppl wont know how to do because they sell out in seconds

New listings on bitmain's site. They're selling the 13.0 TH/s S9 with a PSU for $2k or without a PSU for $1915. I really liked the 13.0 TH/s batches the most since they seemed to be a lot more reliable. They also dropped the T9+ price to $1235, which is quite attractive if you have cheap power.

Hmm u think it is possible for bitmain to influence bitcoin with a fork such that:

-block reward doesnt halve in 2020
-block reward instead gradually increases slowly
-bitcoin mining ends in 2028 instead of 2040 since the rewards are released faster.


End result will be:

-happier miners and more asics sold in the next 10 years
-less energy is used since mining stops at 2028....meaning from 2028 till 2040, no more mining occurs and electricity is saved. I think the world has more than been introduced to blockchain now. We dont need this to continue till 2040 though.

Unless bitcoin skyrockets greatly, when late 2020 comes and bitcoin halves, mining will be even more dead for miners and asic manufacturers.


??

Selling 100 dollar coupons (8units expire 11th June, 14 units expire 1st july) and 125 dollar coupon (2 unit exp 30th June). Selling at 20% of value

1.4 x $0.2 x 24 hrs x 30days = $201 for elect.

Current btc gain from S9 assume 13.5th = 0.0333 a month x $11300= 376

Your profit = 175

Difficulty going to adjust itself in 2 days time, expect profit to drop 10% or so.

unless btc price move north, that about what you be getting.

yes, with even more miner joining from March to May batches, i guess s9 will likely just mine 0.01-0.015 btc by then, cant even pay for the power cost.

Numbers are currently crazy since BTC is stagnating for almost 2 months after "yearly dip", and then "Chinese new year dip". Maybe numbers will change if price goes up. But difficulty increase is killing everything Sad

Ya man, takes at least a good 12 months to roi and by then the btc mined will not be able to pay for power in average home based mining.
