Found @dillongoo's fan animation sadly more satisfying to watch than the second season. #OnePunchMan

A Taste for Health

June 27th, 2019 | Posted by pftq in Stories | #
Had an idea for a story recently for if society found a way to make someone naturally like the taste of healthy foods (like vegetables, etc) - imagine if what you liked and craved lined up with what was good for you.  It sounds and all seems well, everyone eating better diets and enjoying better lifestyles, until unexplained animal attacks start leaving people dead and torn up, seemingly at random and in generally urban settings with no dangerous wild predators.  As the story goes on, footage and evidence start to reveal the attacks seem to come from not any animal but a human.  The authorities track down and arrest one suspect, but the killings continue, seemingly at random and with no motive.  It turns out not to be any one person but people at random who suddenly go mad for human meat.  The commonality is they've all been genetically modified to like the taste of whatever is good for them, and it worked too well.  Because the healthiest food you can...[More]

Bitcoin Calls Below Parity

June 22nd, 2019 | Posted by pftq in Blabberbox | #
Bitcoin is moving so fast that call options on @LedgerX are priced below parity, as if $BTC was still below $11K. Literally free money (just buy the call and sell one Bitcoin to net the difference). #Bitcoin #BTC

USDT Minting

June 16th, 2019 | Posted by pftq in Blabberbox | #
Personal theory on where the #USDT is going - it's actually lent out on #Bitfinex. Risk-free return for the minters while collecting borrow fees during $BTC rallies. The thought came to mind when I noticed a $77M lending wall in their funding page at the same time the $100M USDT headline came out. Other exchanges having increased borrow rates once $BTC broke $9000, but the rates on Bitfinex stayed about the same.

Comparing Options Contracts

June 12th, 2019 | Posted by pftq in Blabberbox | #
This is a spreadsheet I created to compare what call or put options are best to buy, specifically using this for #Bitcoin $BTC options on @LedgerX but can be used with any options really.

Sometimes the further out of money contract actually has less upside than something in the money, and this makes it easier to see.  It also tells you how much money you need to have in another contract to make the same return as the first, so you can have less money tied up in one place.

As a live example using this, you can see currently that the December 15K strike calls for Bitcoin are not worth buying, that you'll make more buying the 10K strike unless Bitcoin goes above $25K by December.  Going up any less would lead to the 10K strike making more.


Using this, you can also find the minimum cash to make $1M on $BTC going to $100K by Dec. 2020:
- $10K strike: $30K
- $25K strike: $12K
- $50K strike: $6K
You lose everything if the strike isn't hit in 1.5 yrs, but you avoid locking up $80K if directly invested in BTC instead.

Flagging Uber, Lyft with QR Codes

June 9th, 2019 | Posted by pftq in Blabberbox | #
For me it's still easier to flag a taxi in #NYC. It'd be great if you can flag @Uber or @Lyft the same way and just swipe QR codes to pay. Then you don't have to wait 5 min for the app to find drivers or for someone else further away to circle the block after accidentally passing you a few times.  Since many drivers already label their cars with Uber or Lyft signs, this is sort of part way there already.  The only thing missing is for a way to pay without driver searching, which would be solved by QR scanning the driver's phone when the passenger steps in to bypass the search process.
