      "body": "# Add email address aliases\n\nThe reason why you should add aliases to your main account is to increase privacy. By means of separating your email accounts and using aliases you increase your privacy and the safety of your data.\n\nTo optimize your privacy make sure you have at least 4 accounts:\n\n1. professional looking account that has your full name/identity: \njohnlocksmith@... (without any jokes, representing trustworthiness)\n2. personal address for offline friends: \njohnlovesyouall@... (people you have actually met in real-life)\n3. personal address for online friends: \njohn9483@... (which uses a random number to protect your full identity).\n4. subscription address for registering on websites / services: \npseudonymousfrog@... (which is vulnerable to hacks and exposed to the entire web).\n\n\n## Hotmail / Outlook\n\nOutlook (hotmail) allows to manage 10 addresses along one main account.\n\nTo generate a new alias:\n\n1. Go to https://account.microsoft.com/ (login if not already)\n\n2. In the navigation bar click on **your info** (or go to https://account.microsoft.com/profile/)\n\n3. Below your emai laddress click on **manage how you sign in**.\n\n4. Click **add email**.\n\n## Yahoo\n\nAllows to create 500 disposable email addresses, each having a unique name appendage.\nThis is great for subscribing for web services and news letters. Basiccally you get to know who is sending you what, and which service has been hacked in cause of unwanted spam. De-registering from a newsletter is as easy as removing the address.\n\n1. From your inbox click on the cog wheel (i.e. Settings)\n\n2. Go to **email addresses** --> **disposable email addresses**\n\n3. Create a pseudonymous base name (i.e. not having any identity-related information)\n\n4. Add alias by appending the base name with something like \"-technews\"\n\nFor every subscription add a new alias for the best possible privacy. \n\nSeparation of both Outlook and Yahoo increases your privacy even more. In that case keep Outlook for messaging and Yahoo for account subscriptions such as newsletters.\n\nMake sure to have different 20-letter securely randomized passwords. For instance, an unshifted password such `misk./49dm[smke'20ano` is a secure password which you can remember within 3 days. A password manager such [KeePass](https://keepass.info/download.html) can also securely store these passwords in case you don't want to type them.",

      "body": "# Optimizing portfolio allocation weights using Zipf's law?\n\n---\n\nWhen investing you would like to optimize the amounts allocated to each asset. You want to have an optimal return to risk ratio, also known as the Sharpe ratio. Can Zipf's law help?\n\n## What is Zipf's Law?\n\nZipf's law states that the second to most frequent occurence in a natural set ocurs about half as much as the most frequent occurence. Zipf's law only works for occurences that vary in the amount of digits. For example, a city can have 112,000 people living in it (i.e. 6 digits), or 22,300,000 people living in it (i.e. 8 digits). So, Zipf's law does not work for body length: 180 cm vs 120 cm (both have 3 digits).\n\n## Investing implementation\n\nAccording to [Ibragimov](http://scholar.harvard.edu/files/ibragimov/files/portfolio_of_diversification_and_value_at_risk_under_thick-tailedness.pdf) (2009) diversification is not preferred for extremely heavy-tailed risk of returns. This is similar to what Warren Buffet has done in his portfolio: about half of his investments is allocated to three assets.\n\nWhen we try to apply Zipf's law in combination with some common sense we can come up with a portfolio allocation for the booming decentralized fintech and blockchain market. The major quote currency is Bitcoin, and the follow-up currency to trade with is Ethereum.\n\nUsing a series like 32%, 16%, 8%, 4%, 2%, and 1% would give us a cumulative top 3 diversifying your assets for 56% of the total portfolio. Market swings can be easily rebalance between these three. Be sure to check whether the price history of your top 3 assets show a neutral or negative correlation. Smaller asset allocations of 2% and 1% target weights can be easily rebalanced when they are under-allocated and underbought by selling some of the over-allocated top 3 assets. This kind of diversification is only preferred when the risk of return distributions are moderately heavy tailed.\n\nYou have to think about it carefully: What would your portfolio allocation strategy be?",
