Buying MKR is like buying virtual bitcoin mining equipment
I think investing in bitcoin mining hardware is a good analogy for buying MKR when the system is live, and I'll summarize how they compare. A bitcoin miner is a tool you buy for a bulk sum up front, and then by doing some work (Maintenance and providing electricity) you can use it to generate income (in the form of bitcoin trickling into your wallet). MKR is similar in that it is a product you buy for a sum of money up front, and then by doing work (performing MKR research and governance) you can generate income with it (in the form of MKR price steadily increasing over time from buy&burn). When you first want to buy a bitcoin miner, you need to carefully analyze the current bitcoin difficulty and compare it to the amount of hashrate you will get from your miner. This is like watching the MKR price and determining when a good time to buy in is. Buying a miner right before there is a huge difficulty increase is like buying MKR at a top right before a correction in the price. This means that even though both assets ostensibly provide a predictable return on their investment, you can still easily end up making the wrong move and be at a net loss. After you've bought your miner, you need to continously maintain and monitor it and provide it with electricity. If you fail to properly maintain your miner it could run into errors that make it temporarily stop mining, or even worse it could just break outright and be beyond repair, losing you your entire investment. This is similar to the responsibility you have after you have bought MKR - you need to constantly monitor the health of the dai credit system and whether the governance process is currently adhering to the scientific consensus on best risk parameters (as well as whether the scientific consensus currently is trustworthy). If you fail to predict a major market event, you could lose a significant portion of your investment. In extreme cases you could lose all of your money in an instant if Maker is grossly mismanaged. And finally, to finish the analogy to include the MKR that currently exists on Ethereum - MKR today is like dormant bitcoin mining hardware that won't work until it has been upgraded with a remote software update (the deployment of the dai credit system). It is possible that the software update will never even get made (analogous to the maker development effort failing and being abandoned), or that it immediately bricks your miner when it is released (analogous to maker suffering a catastrophic failure at launch). In either case you have no guarantee of profits, and are taking a big risk that is contingent on your own due diligence and direct involvement in the project. There is also no legal recourse, because all you bought was a piece of "virtual hardware" (the MKR token), not rights to the software (there is no legal ownership of the dai credit system code, as it is an open source and decentralized project with no contributors bound by contract). If that last paragraph made you really nervous, ill offer some words of comfort: The Maker development team is a highly skilled team of the best solidity developers from all over the world, who have received large amounts of MKR to ensure their continued incentive to be involved in the project. They have been very competent at taking every precaution from the start, and have always focused on security and best practices without any room for compromise. Maker getting unexpectedly hacked is not impossible to rule out, but it would have to be by an elite hacker the like of which the world has never seen before. At the same time I am working on some defensive governance strategies that will maximize the probability of success during the early stages of the dai credit system, and even allow us to recover from massive crash events or getting pwned by a hacker. The key is to keep the outstanding dai very small in comparison to the total MKR market cap during the early stages of the system. Only after years of battle testing and continuous hardening should we allow dai to scale in the way it has the potential to do - it will require patience and vigilance and a strong, coherent and well coordinated community, but if we succeed at this, and prove that we are able to keep the dai credit system operational and efficient without catastrophic failure, we may see dai spread across the planet as the world reserve currency of the 21st century.
Before any difficulty adjustments happen: If Bitcoin Cash gets 12.5% of the hashing power it will have the same capacity as current Bitcoin. If if takes 11.1% of the total hashing power then it will have the same capacity as post-fork, pre-retarget, pre-segwit Bitcoin.
PSA: Adjusted for difficulty, the Bitcoin ABC blockchain is 1 full additional block ahead than the current block count suggests.
According to Fork Monitor Bitcoin SV has achieved 87.723006 Accumulated log2(PoW) at block height 556803. Bitcoin ABC acheived this milestone one block earlier at block height 556802. If you adjust for difficulty, SV is one full additional block behind the current block differential. Update 2: SV is now 2 full additional blocks behind in addition to the current differential when adjusting for difficulty.
Here is a spreadsheet I made for difficulty over the last year (01/16/17 - 01/15/18). Basically it breaks down to an average difficulty increase of 15.1% per month (181.21% total increase), so make sure you're counting on that average when investing in (Bitcoin) cloud mining. It's also likely to continue to rise over the next year as it must keep pace with the network hashrate. Google Sheets
On March 10, the bitcoin network difficulty reached its all-time high of 16.5 trillion. At that time, BTC/USD was trading around $8,000. Hash Rate and Price Dance. After the third bitcoin block halving last month, the bitcoin hash rate dropped nearly 50% from the high of 151.9 Th/s on May 11, the day of halving. How does Bitcoin calculate difficulty? Bitcoin’s network difficulty changes every 2016 blocks. The formula used by the network to calculate difficulty goes like this: difficulty = difficulty_1_target / current_target. In the formula above: target is a 256-bit number. Maximum, current and minimum difficulty . Current difficulty can be found out by using Bitcoin command line 'getDifficulty'. Due to target function not having minimum value maximum difficulty can be calculated only approximately as following: maximum_target / 1 (as 0 would lead the equation to being infinitely big) which is an inconcievable number (~2 to the 224). What is the current difficulty? Current difficulty, as output by Bitcoin's getDifficulty.. Graphs. What is the maximum difficulty? There is no minimum target. The maximum difficulty is roughly: maximum_target / 1 (since 0 would result in infinity), which is a ridiculously huge number (about 2^224). The Bitcoin difficulty chart provides the current Bitcoin difficulty (BTC diff) target as well as a historical data graph visualizing Bitcoin mining difficulty chart values with BTC difficulty adjustments (both increases and decreases) defaulted to today with timeline options of 1 day, 1 week, 1 month, 3 months, 6 months, 1 year, 3 years, and all time
Stocks Greed and Exuberance 5 Things to Watch in Bitcoin This Week
The mining difficulty of Bitcoin is adjusted every two weeks (every 2016 blocks, to be precise) to maintain the normal 10-minute block time. Since June 30, it was below 10 minutes and dropped ... We will review the current Bitcoin mining profitability, network difficulty and hashrate, and illustrate the difference in passive income/mining revenue from mining Bitcoin in their house and how ... We will review current Bitcoin mining profitability, network difficulty, the upcoming halving, and illustrate the difference in passive income/mining revenue from someone mining Bitcoin in their ... To calculate New Difficulty Target, take old difficulty target X 20160 minutes (which is amount of time in minutes for 2 weeks) Divided by the time in minutes of the last 2016 blocks. 01:18 Market Update 02:18 BTC Difficulty and Hash Rate Drop 05:01 Satoshi Nakomoto Won't Sell Bitcoin 07:28 eToro Market Analysis 10:59 Paxful in India 13:36 IOST NFT Collectibles and Mystery Box ...
