Currency, in general, is a medium for exchange that is based on promises for what that currency is worth. Commonly called "money." Cryptocurrency is not centrally controlled or regulated and their value is based on the supply and demand; there are built-in limits for how much can exist (potentially curbs devaluation), public logs of the transactions (blockchain) and the cryptography algorithm make it difficult to counterfeit. Maybe this old TechQuickie can explain it better. TL:dr an unregulated form of digital money
What is mining?
The most basic way to acquire a cryptocurrency is the same as acquiring money, in exchange for goods or services. The other way to get cryptocurrency is by mining, or solving increasingly difficult math problems in exchange for the cryptocurrency.
What does this have to do with GPU prices going up?
Crypto mining started on CPUs, but it didn't take long for people to realize that GPUs, especially the 'heavy duty' ones intended for gaming, are really good at it. The downside to GPU mining is heat and power consumption, this lead to mining systems designed for the task and eventually ASIC chips designed just for mining. As a cryptocurrency matures the math problems become very difficult, leading to pools of miners that share resources - this has also lead to some malware using infected systems for mining. An older currency like Bitcoin is well into that 'pooled specialty hardware' age, but newer options like Ethereum are aimed at GPUs; this increased demand means lower supply which means higher prices.
When will prices go back to normal?
Probably if or when the cost to mine via GPU exceeds expected returns. There are some specialized cards set to hit the market which may ease the demand on enthusiast GPUs. A word of warning, when this happens the market will be flooded with GPUs that were used for mining. The lower price may seem attractive, but these cards have been used in harsh conditions, 24/7 for who knows how long. Mining cards probably won't run very well/very long or they could work fine. You have to decide if it's worth the risk.
Should I start mining?
That is entirely up to you, but please take some time to educate yourself on the risks and benefits before you decide. Take a look at a profitability estimator to get an idea of what you might expect. These cryptocurrencies can be very, very volatile so don't quit your job expecting to strike it big with mining. Consider the cost of taxes, cooling, hardware, replacement hardware, and power. Mining is hard on hardware, the wear and tear means things like fans, the GPU(s), and other parts may die prematurely. Keeping your hardware cool (about 300W to cool 1000W) can lead to additional costs for hardware and power or reduced output. The cost of electricity may not seem like much, but it can be enough to make or break a mining setup. Take the time to figure out your ROI.
Should I sell my card?
Again, this is entirely up to you. There may be situations where selling a card and upgrading with the money can work out, but there are a lot of factors at play there, so do your research. Check selling sites: eBay, Craigslist, hardwareswap, LetGo, Facebook, and other (similar) selling sites for pricing. If shipping, package it how you bought it: clean, inside an anti-static bag, in a cardboard box with some padding. If meeting someone IRL, be careful, meet in a well-lit public place - some areas have exchange locations at places like police stations. I'd like to take a quick moment to thank Linux_PCMR for some insight, Graphics_Nerd for gathering some links for review, and the kind users that have replied to the number of posts on this subject.
I just bought my first ASIC's, did I make a bad investment
I bought 2 brand New s9i's with psu's For 1600$ And I also Will build a sound Box And I need a router that supports my mobile broadband, this Will prob. Cost another 200$. So the calculating speed is going to be avarage 28TH. How long Will it take to get my money Back when I don't have any electricity Costs. Im just bit concerned because my friend told me that according to BitcoinWisdom site my profits Will cut half every month And that I Will only be making the amount what Bitcoin profitability calc. For the first month. So on few months after mining im making just a fraction of the profit And never going to be able to get the ROI? Can somebody help me and tell me a simple answer how this difficulty affects my New investment.
Cross posted to: /litecoin I'm on verge of buying the bitmain l3+ which I would receive in November. I've read the difficulty will blow up soon and profitability will crash. Since I'd have to wait 3 months before receiving my unit do you think I'd be able to get a return on investment? Been running calcs all day and it looks good today but not sure about on three months and beyond. Thoughts? Should I just buy Ltc and hold at this point? I have made enough in bitcoin investments to pay for the unit and understand the risk. Thanks! Ps I'd be happy to break even honestly Pps. How loud are these L3+s? Like a large vacuum cleaner really? Edit: clarity Update: although I was feeling confident I'd get my roi within a good about if time, the sound and heat issue in my tiny condo was the deciding factor. I didnt make a purchase and will hodl my btc until another quieter investment opportunity crops up. Thanks for all for advice!
I understand that BC mining isn't exactly lucrative when done on a small scale, but I do have a more practical question. It seems that one of the biggest costs is A/C. Well I live in Northern Canada, and it sometimes gets to be -50 here in the winter. Would it be reasonable that profit, or ROI could be greatly increased by running a 6 month operation, by opening a window? edit: forgot to mention that we pay about 100-150 in heating per month; so I was thinking of a two birds one stone. The idea would be to invest maybe 2-5k in equipment, and even if I don't have to heat and don't mine a single BC, I would be saving about 800 a year in electricity due to no longer needing to heat. edit2: here's the calcs I came up with for this product https://www.amazon.ca/AntMiner-T9-11-5TH-0-126W-Bitcoin/dp/B01NCX6ZPO/ref=sr_1_7?ie=UTF8&qid=1485137997&sr=8-7&keywords=antminer http://www.coinwarz.com/calculators/bitcoin-mining-calculato?h=11500.00&p=1450.00&pc=0.09&pf=0.00&d=392963262344.37000000&r=12.50000000&er=927.60000000&hc=0.00 Total estimated profit : $1,348.33 USD: or about 1.8 years; however, add the about 800 CAD I spend on heating my place, this becomes about 1900 USD, or about 1.4 years (estimated). That'd be like buying a stock with a 75% dividend yield. Any thoughts? edit 3: forgot that I could only reasonably run this for 6-8 months out of the year, so approximately a 2 year ROI. Still, that's pretty damn good if you ask me, no?
Bitcoin and renewable energy are like two peas in a pod.
I’d love to hear your thoughts on this; please check my logic and offer anything that i may be missing. Assuming we look at renewable energy investments in a deflationary environment compared to a inflationary environment where all other things are equal, renewables become much more attractive. Scenario: What is the payback on a 1 million units investment in renewables where the purchasing power of the currency declines by 2% YOY and the ROI on initial principal is 4 years? 1,000,000 in purchasing power after 4 years is 922368.2 If the ROI payback of the 1,000,000 is 4 years BUT the purchasing power of the 1,000,000 has lost 77,631.84 in that time then one did not truly return the investment. So one needs to operate the system for an additional 3.7 months to arrive at a realized ROI or purchasing power of the initial capital. Looking at it from a deflationary angle, the reverse of the above is true. One would be able to recoup their investment approx. 4 months earlier and in a true 4 years’ time one would have 82,432.16 more purchasing power in a deflationary environment. Here’s the kicker: Play this scenario out for 30 years (lifespan of solar panels) and the realized savings (purchasing power of the savings through the life of the investment) for each economic environment assuming savings of 250,000 units per year are: Inflationary: 5,005,406 Constant: 6,250,000 Deflationary: 8,586,081 I cheated a little with the numbers because I started the calc on year 5 as though both truly did return initial principal but its close enough to show the delta. TLDR; Bitcoin encourages long term investments, such as renewable resources.
I personally stick to buy and hold but was asked by a family-member if this offer was worth it: Hosted 2TH/s at $2k per year. Available to customer upon payment. Prepaid for the year, I am certain. Other options were, if i recall, something like 1MH/s for $15/month. I had initially told him to look into altcoin mining, if he just had to mine something. Then he came back with this "proposal" from some business he had connections with. (that he even had btc relevant connections surprised me but then again, the bitcoin subs are filled with ppl from every walk of life.) I simply don't know enough to make judgement calls on profit-calcs. However, what he showed me, seemed to indicate that he could make a profit even while difficulty was exponentially increasing at 100% per month. He was all excited about it, ready to sign a check. I managed to get him to hold off on doing anything until his lawyer was able to review the contract. Obviously his lawyer is no bitcoin guru either, so I am looking to anyone that could, with the limited info available, say: RUN AWAY or KEEP LISTENING. Or, if you can, tell me if this can actually produce a ROI or if it is another attempt to make easy money of the noobs. $2k is not going to make him homeless by any means but I just don't know if this is something I should encourage or not. thanks
