datzenmike Posted February 8, 2018 Report Share Posted February 8, 2018 I look at it this way. We are already (certainly in Australia) moving towards a cashless society. I plan to put about $1k into bitcoin (or one of the other crypto currencies, I haven’t decided which yet). If it really does take off, well it’s an experiment that’s worked. If I lose my money, meh, it’s only a thousand dollars and nothing I’m going to cut my wrists over. What's you $5k worth right now? Quote Link to comment

125 CSL Posted February 10, 2018 Report Share Posted February 10, 2018 mining rundown https://steemit.com/cryptocurrency/@mountainherb/so-you-want-to-start-a-bitcoin-mine Warning – Herein Be Math In my last post, I gave an overview of bitcoin mining as an investment. In particular, I compared two ways of acquiring bitcoin, mining and purchasing, in a qualitative hand-waving manner. In this post, I dig a little deeper into mining and how it works, and things you need to know as a potential or newish miner. I will show how to free yourself from online mining calculators, using junior-high mathematics. In full disclosure, I'm a newish miner myself, sharing what I've learned and experienced, and I hope rehashing it in a slightly different way. Bitcoin Mining and Factors Affecting Production and Revenue Skip if you already know this. Mining starts with laying out some cash to buy mining production capacity, measured in hashes per second. A hash is a computing operation essential to solving the decryption problem that yields bitcoin. You need a lot of them, so the rate (let's call it H) is usually expressed in gigahash (GH, a billion hashes) or terahash (TH, a trillion hashes) per second. You can get them from an ASIC (application-specific integrated circuit, if you must know) mining machine, like Bitmain's Antminer S9, or by contracting it out to the cloud through a provider like Hashflare or Genesis Mining. (Second warning: I'm defining symbols. Can an equation be far off?) Immediately your mine starts crunching hashes, working to solve blocks in the chain and bring up the coveted block reward (B, currently 12.5 BTC). You get no partial credit for solving a block. First miner to solve it gets the reward, and miners compete furiously to find a bitcoin nugget worth over $100,000. Working on your own, you will never do it. For that reason, mining pools exist. You contribute your hashpower to a pool, and its combined hashrate keeps you in the game. Periodically, the pool shares out its haul. They have various formulae for figuring your share, but it's usually proportional to the hashrate you contribute. And of course, the pool takes a bit off the top (P, typically about 2%) for providing service. By design, the bitcoin system regulates the rate of bitcoin production to about one block every ten minutes. It does so by adjusting the difficulty (D) of the block decryption problem. Every 2,016 blocks, the network calculates a new D meant to reset the block solution time to ten minutes. As of today (3 Feb 2018), D = 2,603,077,300,218. Over the past 24 hours, that difficulty held the block solution time at 8.61 minutes against a total network hashpower of about 20 million TH/s (that's right, 2 x 10^19 hash/s). Expect the next adjustment to D around 9 February. You can find the current value and history of D, along with many other network-related facts and figures, at https://blockchain.info/stats. Mining writers often overlook another potential source of mining revenue: transaction fees (F). The blocks miners compete to solve comprise batches of bitcoin transactions, each of which incurred a fee. That fee goes to the miners who solved the block, and it varies from block to block. Most pools keep the transaction fees for themselves, but a few (notably Slushpool) share them out along with the block rewards. Paying the Piper Not only must you shell out up front for mining capacity, but wait, there's more. Hashing requires electricity, and equipment requires maintenance. These constitute the main ongoing operating expenses of a bitcoin mine. Your mine must produce enough bitcoin to pay its operating expenses, or you have to shut it down. I'll write more about operating expenses in a future post. Final Warning, Here Comes the Math Buried under all the complex math of the bitcoin blockchain lies a fairly simple formula for the expected value of mining yield (Y, in BTC/s): Y = B H / D / (2^32 hash) . Reality check: Let's plug in the figures for the entire network, and see how many bitcoin emerge from the ether in 8.61 minutes. Y x (60x8.61) s = 8.61 x 60 s x 12.5 BTC x 2.03x10^19 hash/s / 2.60x10^12 / 2^32 hash = 11.7 BTC That falls a little short of the expected 12.5 BTC, probably due to using 24-hour averages for the block time and network hashrate. In one day, 86,400s, the estimated daily bitcoin yield is then Y x 86400 s = 86400 s x B H / D / (2^32 hash) = B H / D / 49710. If you keep track of such things, the constant 49,710 has units of hashes/second. If you express H in terahash/second and D in trillions (currently 2.603 trillion), the 'H/D' part is much easier to deal with. Pay No Attention to the Man Behind the Curtain All of the common mining calculators use this same formula. If you have any skill with spreadsheets, you don't need online calculators any more. Enjoy your new freedom! To verify at the calculator of your choice, enter zero for the cost of equipment, electricity usage, and pool fee. If it needs an exchange rate, use $1. See what it gives you for a 1 TH/s (1000 GH/s) hashrate. Compare to my formula, making sure you and the online calculator use the same block reward and difficulty. Please let me know if they don't match! What Does All This Mean to Me? As a miner, you can estimate your daily mining revenue (R) in bitcoin using R = (1-P) (Y x 86,400 s + F) = (1-P) (B H / D / 49710 + F) . In words, you get daily block rewards based on your mine's hashrate, plus whatever transaction fees your pool shares with you, reduced by the percentage the pool takes. Actual results will fluctuate with the total network hashrate, and random variations in your pool's ability to find the solution before anyone else. To convert to fiat currency, just multiply R by the appropriate exchange rate (E). Ignoring for now transaction-fee income, we come to an Important Truth about mining. In fiat terms, the main source of mining revenue, block rewards, is proportional to E/D (exchange rate divided by mining difficulty). If the two keep pace with each other (going up or down), top-line mining income (before capital and operating expenses) remains fairly stable. In 2018 so far, the US dollar exchange rate has declined while the difficulty increased. That spelled doubly bad news for miners. Quote Link to comment

racerx Posted February 10, 2018 Report Share Posted February 10, 2018 Yes and no, you have to invest in real estate, 401k, 403b, know needs and wants, don't let emotions invest for you. Do your homework, learn from history..i.e. Bitcoin and the gold miners in san Francisco, the ones who made out were not the miners but who provided services, sold tools and equipment. The vast majority of miners went broke. Also learn from economic bubbles and importantly derivatives. People made tons of money betting against the grain. Quote Link to comment

paradime Posted February 11, 2018 Report Share Posted February 11, 2018 Put it this way RTW, although they were a major contributor in creating it, after the 2008 banking crash Goldman Sacks was deemed "too big to fail" and baled out to the tune of $182 billion in US taxpayer dollars. Then Bush appointed Goldman Sacks CEO Ben Bernanke chairman of the US Federal Reserve, and today five ex Goldman bankers are in Trumps cabinet. To say this firm represents the banking establishment's best interests is an understatement. The very financial establishment bitcoin is trying to circumvent. Serious conflict of interest with respect to objective analysis of cryptocurrencies. Quote Link to comment
