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.

Conversations

Overhead a couple people having one of the more interesting philosophical conversations in a long time and wanted to join in, only to then realize they were middle school students doing homework. Sigh.

Saitama vs Suiryu Fan Animation

May 26th, 2019 | Posted by pftq in Blabberbox | #
Thought this fan animation was more exciting to watch than the actual scene in the anime, which sadly often felt more like still images panned across the screen. #onepunchman

Brightburn at Dolby Cinema

May 25th, 2019 | Posted by pftq in Blabberbox | #
Just watched @Brightburn but was actually more impressed by @DolbyCinema. The bass was so heavy + directional that it felt like the sensation of a train speeding by (or coming right at you), which made it scarier than the scene itself.

Conversation with a Doctor

May 24th, 2019 | Posted by pftq in Society | #
One of the more frustrating experiences I've had in a while... part of what makes the healthcare here feel pretty worthless.  Obviously not reflective of all doctors... just many my own experiences.
-------------
Doctor: Here's a prescription drug that will relieve the symptom.  Just take it everyday from now on, and you won't feel it anymore.
Me: Is there a test or something we can do to check why it's happening? Or if it might be more serious?
Doctor: Like what?
Me: Maybe it's...[More]

If People Talked About Internet Like They Do Blockchain

May 10th, 2019 | Posted by pftq in Society | #
Person B: Have you heard of this thing called the Internet? It's the future. You should buy as many dial-up modems as you can before the price goes up.  Once the Internet becomes mainstream, we'll all be rich.
Person A: Why would the price go up?
Person B: Because adoption.  Everyone will start using the Internet.  You could use it to store information, transact, compute things... everything will be on the Internet.
Person A: Isn't that just computers in general?
Person B: No, unlike just your home computer, anything that is on the Internet stays there forever.  It's also decentralized, meaning no one can shut it down or control it.  And most importantly, it's global.  Everything has to be global nowadays.  That's the future.  Personal computing was the first revolution.  This is the next one.  Imagine if you could go back in time to the 80's before personal computing was mainstream.  This is that...[More]

Prions and Synthesized Foods

April 23rd, 2019 | Posted by pftq in Blabberbox | #
More an open-ended question here.  Prions, or misfolded proteins, are the cause of mad-cow disease when eating meat.  The animal itself is more likely to be produce misfolded proteins when eating brain tissue, but sometimes it's also just luck (or perhaps environmental, stress, etc).  The prions themselves cannot be destroyed by heating or other means once created, as it's more a mutation than a "disease." Once in the body, it causes other proteins to be misfolded as well in a tumor-like fashion.  With regards to new synthesized foods like vegan or fake meats,  I wonder what ways (if any) are there to unintentionally create misfolded proteins in the process as well.  Right now, it seems that they try to mess with the vegetable ingredients as little as possible when creating the meat flavor and texture.  Some of these opt for a non-GMO label to make it distinct.  It would probably be more a concern if in the future companies become more aggressive with manipulating or modifying the proteins themselves as they refine the meat.
