[So no ICO, no sales, no scam.]

The word Triskaidekaphobia means fear of the number thirteen. The word is an amalgamation of the words "treiskaídeka" meaning thirteen and "phobos" meaning fear. In many societies including ancient and modern the number thirteen have been associated with unpleasantness or fear. Even today you will find many buildings across the world don't have a designated floor number thirteen (there of course is an actual thirteenth floor but let's not go into that discussion). Some interesting incidents from wikipedia:
1. Apollo 13 was launched on April 11, 1970 at 13:13:00 CST and suffered an oxygen tank explosion on April 13 at 21:07:53 CST. However it returned safely to Earth on April 17.
2. Vehicle registration plates in the Republic of Ireland are such that the first two digits represent the year of registration of the vehicle (i.e., 11 is a 2011 registered car, 12 is 2012, and so on). In 2012, there were concerns among members of the Society of the Irish Motor Industry (SIMI) that the prospect of having "13" registered vehicles might discourage motorists from buying new cars because of superstition surrounding the number thirteen, and that car sales and the motor industry (which was already failing) would suffer as a result. The government, in consultation with SIMI, introduced a system whereby 2013 registered vehicles would have their registration plates' age identifier string modified to read "131" for vehicles registered in the first six months of 2013 and "132" for those registered in the latter six months of the year.

I am launching an experimental deflationary ERC20 with the name "Triskaidekaphobia". The token will be 100% airdropped through an auto minting function (mechanism explained below) and will stop after the maximum supply cap is hit. So no ICO, no sales, no scam. In fact the smart contract will reject the transaction if you try to send any ethers to the contract. Supply will start at zero tokens and I will wait till the first airdrop is claimed by someone else before I mint any tokens through the airdrop.

To claim the airdrop, all you have to do is to send a zero ether transaction to the contract address (0x73AA6B881552451eEBa7533a1A58b297Ed549F3C) with a high gas limit (300,000 or above is recommended - if you are using metamask, edit the default gas limit through advanced options or your transaction will fail). Once confirmed, you will find tokens in the same address from which you sent the transaction. The airdrop will start at 9,500 tokens/transaction and will go down by 1% after each successful airdrop until the maximum supply of 1 million tokens is reached. At 1 million the token minting stops permanently.  

Once 50 airdrops have been claimed (equivalent to 400,000 tokens being minted) the contract will gamify the token keeping it true to its name. After first 50 airdrops, every non-zero value transaction will cause the 13th largest token holder's balance to be slashed to 1/3rd the original value. Of the 2/3rd slashed, 1/3rd will go to the next largest holder (14th largest holder) and the other 1/3rd will be burned. Remember - only non-zero transfers will enable this slashing, neither minting, nor anything else. The reward to the 14th largest holder is intended to remove the certainty in ranking for the next round.

One quick thing however - please make sure you put high gas limit for all transfers so that the complex token logic can be executed without running out of gas (300,000 or above is recommended). Most of the times you will receive a handsome refund of gas and so your transactions are not going to be too expensive. I have tried to optimize the code as much as possible but ranking essentially means looping which needs gas to run.

There is a 5% developer fee with each minting event. So even the developer token pool starts at zero and only keeps pace with the overall supply. I haven't decided what I want to do with the dev fee yet but I am open to suggestions. Everything is on the blockchain for easy verification by everyone.

Now disclaimers:  
1. Please don't use this token to invest any significant sum of money. This's meant to be a game and fun rather than SoV
2. The code hasn't been audited by any specialist and so not guaranteed against sophisticated attacks. I have observed basic hygiene factors and best practices however
3. I am not selling or guaranteeing anything. If the code breaks, all I can promise is I will learn and try again. I haven't kept any owner backdoor in the code intentionally
