📌 Introduction
If anyone in crypto has turned “slow” into a creed, it’s Charles Hoskinson. At 26, he left the fledgling Ethereum and set out to build Cardano and ADA using an approach of “write the papers first, then write the code.” While his peers were racing to iterate, he was racing to publish papers—this “academic” approach remains one of a kind in crypto to this day.
👤 Who Is He?
Charles Hoskinson, born on November 5, 1987, on Maui, Hawaii, USA, studied mathematics, specializing in analytic number theory. He attended Metropolitan State University of Denver and the University of Colorado Boulder, but left his PhD unfinished to dive headfirst into crypto. He was one of Ethereum’s earliest co-founders and later founded Cardano (ADA). Today, he leads Input Output (IOG, formerly IOHK), the engineering company behind it.

📌 Introduction
When trading trends, two things are especially risky: “refusing to exit after making a profit and giving it all back,” and “holding on stubbornly through a loss until it turns into a deep drawdown.” Most indicators teach you how to spot the direction, but don’t tell you “when to get off the ride.” That’s exactly what SAR is for—it doesn’t predict tops or bottoms; it simply keeps an eye on the door while you’re riding the trend, helping you get off when it’s time. Its full name is Stop and Reverse, and it’s commonly known in the industry as the “Parabolic Indicator.” In a nutshell, it’s an “automatic stop-loss manager” for your trend trades.
💡 What exactly is it?

📌 Introduction
In 2009, a programmer who had been rejected by the art world, frustrated that he “couldn’t sell his paintings,” teamed up with a partner to tinker with a little card-swiping square. More than a decade later, that little square had grown into a payments giant that even changed its company name to “Block.” Its boss is the person in all of Silicon Valley most willing to put “I believe in only one coin” into the company charter. That person is Jack Dorsey.
👤 Who Is He?
Jack Dorsey was born on November 19, 1976, in St. Louis, Missouri, USA. He is the co-founder of Twitter (now X) and the founder and CEO of Square, later renamed Block. In crypto circles, he has an even more prominent label: “Bitcoin maximalist.” He publicly backs only Bitcoin and is basically “not interested” in other altcoins, Ethereum, or NFTs. His net worth once reached around $4.5 billion, making him one of the tech billionaires who has most thoroughly put his beliefs into practice through his products.

📌 Introduction
When people look at indicators, their first question is often “Is it going up or down?” But there’s a more fundamental question than direction: Is there a trend at all right now? Is the market moving along a path, or just spinning its wheels? You may be able to make up for getting the direction wrong with discipline, but if you’re wrong about whether there’s a trend, your entire strategy is flawed from the ground up. That’s what ADX does—it doesn’t try to guess whether prices will rise or fall; it just tells you “how much strength the current move has.” Use other indicators to gauge direction, and ADX to measure strength.
💡 What exactly is it?
ADX stands for Average Directional Index. In plain terms, it’s a “trend strength meter”: on a scale from 0 to 100, a higher value means the current price movement is more directional and has more momentum; a lower value means the market has less direction and is more like stagnant water, sloshing around in place. The most counterintuitive thing about it is this: a high ADX doesn’t mean the price is necessarily rising; it only means “the price is pushing hard in some direction.” A low ADX doesn’t mean the price is about to fall either; it just means “nobody’s pushing very hard, and the market is grinding sideways.” Think of it like a barbell at the gym—a heavy barbell (high ADX) means someone is training seriously (there’s a trend); a light barbell (low ADX) means everyone is slacking off (the market is choppy). To tell whether they’re training chest or legs (whether the price is rising or falling), you’ll need another machine.
