Bitcoin is "secure" until P!=NP.
if someone one day finds out that P is equal to NP, then bitcoin will not be safe anymore.
But if this happends also everything that atm is considered secure will not be anymore (e.g. homebanking).
Apart from that, Bitcoin is not just cryptography.
There are many companies that allow users to purchase sell and manage bitcoins, if their servers are not secure, then also bitcoins that they manage are not secure and can be stealed.
Moreover, Social Engineering is always there, waiting for you to make a mistake.
So, Bitcoin is secure? In my opinion, the answer is no. Nothing is secure because humans are weak, easy to control, and most of the time: Stupid.

Dont buy ANYTHING with prices as stupid as they are now.
That price is twice what it was which means you are going to have to mine twice as long as you should to even start making money. Long enough in fact that GPU prices will probably go back down and you are going to regret ever getting into mining.
New stocks of GPU look like coming online during February.
Nvidia has started a scheme that should allow ordinary customers, miners or gamers (not 1000+ GPU farms)to buy one or two cards directly at more realistic prices.
Sit tight.
See if it happens.

I've been able to get a bonus of 500 in a certain shop... so i would pay this cards 110.
That's why i would like to JUMP on the train now..
All the things should cost max 400 (Mobo,gpu,cpu,ram,psu,ssd)
Can't you upgrade your Vega 56 into a 64 with a BIOS flashing? In that case, you should benchmark the nvidia against the Vega 64...
According to whattomine their are pretty much the same in terms of earnings..
Vega is outstanding at Cryptonight, very good at Ethash, and piss-poor at pretty much everything else. If you plan to do any Equihash, Neoscrypt or, especially, Lyra2v2 mining then get the 1080.
I really don't know which one i should buy.. According to whattomine i should instantly take vega56, according to nicehash gtx 1080.
I've read of troubles about vega56. But i don't know if that's a standard thing for each card or not.
I'm confused
In a vacuum the Vega is strictly a better mining card. In a head to head comparison I'd always take the Vega. You should take into account that they can be a pain to configure and users here have reported several issues with crashes. If you're willing to do the extra work you'll get better rewards from Vega.
This thing of crashes on Vega really scary me. I've just read 10-15 posts on google.. It would be nice to know more about some Vega users.. Does everyone have problems?
I can get both at the same price, 610 each one.
Which one should i choose? - According to whattomine, Vega56 makes 2$ more than Gtx1080, but when i look at the nicehash calculator this things are upside down, gtx 1080 makes better than vega56.
Which one do you suggest? What makes more money ?
Thank you

Stupid question,
What is the formula? HashRate * Something * SomethingElse / SomethingElse2?
What are the main variable involved? Difficulty, exchange ratio...
could you please give me an example?
Thanks

Thank you guys, i'll pick the Ti tomorrow, i hope that this will be still available. Do you know a good mobo under 100 that i can use? I had find Asrock H81 Pro BTC R2.0 but unfortunately it is now sold out everywhere
For a single card? Pretty much any modern mobo will work. If you want to future proof, get one with 6-8 pcie slots minimum.
For my builds I went cheap: a GIGABYTE GA-H110-D3A and a BIOSTAR TB250-BTC+, both with cheap Celeron CPUs and single 4gb sticks of RAM. Does the damage just fine, at least using Ethos. Boot times are a little slow but once everything starts chugging away you can't tell the difference and the power consumption is good and low...
They are both out of stock and overpriced here in Italy..
Especially the BIOSTAR, that cost something like 230.. I have to find an alternative :/ On Ebay there are some Asrock H81 PRO BTC that comes from China at a very ridicolous price 45, But it's probably not safe to order from there (Becouse of time, orders from china always keep 30-45days to come here) I'd rather get 1080 instead. Right now it's only about $20-ish more than 1070Ti, but has the same TDP as 1070Ti, and gives significant more hashrate (okay, probably not for memory-intensive algos like ETH...)
Yes, i've find only cards 1080 that costs 100-150 more than the one i find. Unfortunately this is too expensive for my estimated budget. :/

The 1070 ti should be your best bet. Specific prices would help out a lot though. What sort of price difference are we talking about here?
515 1070 Ti
509 1070 Gigabyte
550 1070 PNY
Do you think i should still go for 1070 ti?
The thigs that sound "strange" to me is the fact that this 1070 ti has lower prices than the others on the market. Do you know if there are some known problem with that? or if it requires some particolar hardware behind?
I can choose one of them,
1) MSI GeForce GTX 1070 Ti 8 GB AERO
2) GIGABYTE GeForce GTX 1070 AORUS 8 GB
3) PNY GeForce GTX 1070 8GB
They are all in the same range price, which one has the best performance in mining?

Hello guys,
I'm trying to find more infos about estimation profit of whattomine.com.
A friend, told me that this values are so MUCH estimated.
Accord to this website,if i take the most profitable coin atm (GoByte), if i start mine today with a gtx 1070 i get 500kh/s in NeoScrypt, considering a cost of 0.1$ KwH then i can make $8.43 dollars a day, means, 220$ a month.
Do you feel confident with this values? Or this is way too esagerated as my friend told? Is it possible to know the baddest profit for this card (the worst case)? or calculate it based on the previous 30 days period?

You definitely want to overbudget when you're looking at PSU ratings, especially for 24/7 mining. Running a PSU 24/7 close to its maximum is asking for trouble.
In general, you don't want to exceed about 70-80% of the PSU's rated capabilities. Buying a PSU capable of delivering more power does not cause you to use more power, but do note that most PSUs reach optimal efficiency if they're loaded somewhere around 50% of the rating. (For a better 80+ PSUs, this becomes less noticeable.)
Add up the TDP of the CPU and all of your graphics cards, under the assumption that you don't have an unusually high number of drives or fans. Then multiply the sum by 1.25-1.4 (subjective), and you have a rough estimate of what you're looking for (generally round up to the nearest typical PSU rating, but you could round down if the difference is small enough). You can usually get by with less, especially if you mess with clock & power settings, but that's for you to play around with.
Also check for the number of connectors, particularly PCIe 6-pin or 8-pin connectors. These are necessary for powerful cards in a multi-GPU system.
Look for PSUs with the guts manufactured by Seasonic, SuperFlower, FSP, Delta, or another reputable manufacturer. Most upper-end units from brands such as EVGA are made by one of these.
Those made by HEC, CWT, Sirfa/Sirtec are lower on the totem pole, but *usually* do okay. CWT especially has gotten better since they partnered with Corsair a few years back. However, for heavy 24/7 loads, I usually look for the OEMs in the above tier.
Those made by unknown OEMs should generally be avoided. Perhaps they'll be okay, or they'll fail. Worst case involves a crappy PSU damaging your other components.

Thanks man ! This seems pretty clear.
So, Assuming i've this configuration:
Mobo: H81 Pro BTC v2.0
CPU: Intel G1840
RAM: 1x4gb
GPU: 1x Sapphire Radeon RX 580 8GB GDDR5 PULSE
Intel G1840 has a TDP of 53W.
Sapphire Radeon RX 580 8GB GDDR5 PULSE has a TDP of 185.
I sum up: 238, then multiply per 1.4 = 333.2
1) If i decide to buy a 500W PSU than 70% (500*70/100) this will result in 350W so 20W of margin from estimations
2) If i decide to buy a 450W PSU than 70% (450*70/100) this will result in 315W so -16.2W from estimations.
While 2) should be good too, 1) for sure good. So the PSU should be greater than 500W.
According to amazon the best option is Corsair 550W at 44 shipped
This comes with the cable needed for Radeon RX 580 8GB GDDR5 PULSE that is 1x8pin and my psu has 2 of it, So OK
This is it.. right? Thanks again for your patience
If you're certain that you're going to expand, then it may be worth considering higher-end PSUs, at least beyond 500W. For example, it's usually the case that up until around 850W, bigger PSUs give you more watts per dollar. (Over 850-1000W ish, the prices start increasing more rapidly than capacity, which makes 2x PSUs worth considering)
Make sure to ground the PSU cases to eachother..
How this should be done?

How can i calculate what PSU i need in order to run my entire rig? What should i consider in order to find the right one? and how to be sure that the result will be scalable?
I've a very low bugdet, so i would like to start with just 1 GPU and then add the others as soon as i make some profit.
What PSU should i consider for 1x rx 580? or 1x gtx 1080?
If i buy a PSU with more watt than i need, does it consume more or just take "what it needs"?
This are very noob question, hope you can help me.. Thanks

Yes, i did.
If i search i find the result "as is", i would like to know the reasoning or a formula that would help me to be autonomous.

Thank you for your answer,
Yeah, i know electricity costs are really high.
I've also give a look to other gpus but this 3x 7950 seems to be the best in terms of ROI.
I've seen many "deals" for new gpus but they starts from 270 and the ROI of a rig is higher, at least 3/4 months.
Are this the usual times when trying to build a rig from scratch?

Hello everybody,
I've find a guy that is selling 3xRadeon HD 7950 at 230. I'm thinking about buying them and create from scratch my first mining rig.
According to nicehash this still seems to be profitable. My bills are 0.22 Kw/h and this would let me earn about 150 per m.
Considering, i've to buy every other component of the rig, is this an option or not? If not, what do you suggest for a starter like me?
