Ask Doctor Bitcoin: This Dallas Entrepreneur and Blockchain Expert Offers Free Advice for Emerging Crypto Market » Dallas Innovates –


When Coinbase’s shot up to more than $400 a share on its first day of trading—well above it’s predicted market open—Mark Hopkins was instantly inspired.

He quickly penned the latest iteration of his eponymous “Ask Doctor Bitcoin” column, aptly named after the week’s hottest news: “How do I explain Bitcoin to my friends?” Here’s some handy tips:

  • Bitcoin is the reference architecture for blockchain, which is an internet protocol designed for mitigating or removing the requirement for trust between counterparties.
  • Reference architecture: a name for an implementation of an idea that you can use as an ideal template for the thing it’s a reference for.
  • Protocol: name for a type of software or networking technology that represents a class of software.
  • Remember, real world examples where trust requirements are a problem trump theoretical futuristic possibilities when explaining things. That’s why people always say: “Bitcoin fixes this.”


Hopkins, who is a local serial entrepreneur, blockchain expert, and journalist, publishes the weekly blog on paid newsletter platform Substack. He previously helmed the Roger Wilco Agency, a creative agency focused on content marketing, and served as a consultant across Dallas’ blockchain and startup community.

Before that, he covered technology for Forbes, TheCUBE and Mashable, and covered startups and crypto at SiliconANGLE and LaunchDFW.

Launched in 2013, the “Doctor Bitcoin” brand is a way for Hopkins to offer his years of expertise as a vital educational tool during major news events.

For instance—he sees the cryptocurrency, blockchain, and bitcoin space as one that’s sat on the “bleeding edge for a while.” But, it’s also a space that has begun to come into its own, in a way that Hopkins calls a “serious arrow in the quiver of the enterprise and institutional investors.”

But recently, a new technology has come into the limelight. Hopkins even says it was incepted here in Dallas.

It’s non-fungible tokens, or NFTs.

“I spent probably more time than most working with and researching NFTs when I was CTO with Veritoken,” Hopkins told Dallas Innovates. “It’s fascinating that the art market has succeeded in what our goal was there: popularizing and standardizing NFTs.”

Hopkins time at Veritoken, a local blockchain company, came when they ‘acqui-hired’ the Roger Wilco crew in early 2019. According to Hopkins, the team’s goal was to take the technology concept of NFTs and use them as tools to standardize trustless transactions across a variety of industries. 

“In light of how popular NFTs are now, Veritoken’s demise is even more heartbreaking than it was in 2019,” Hopkins says. “Ultimately, that gave me the freedom to be choosy about my next few projects, which has led to some really fun experiments in blockchain, AI, 3D printing and journalism.”

“I just finished working on an AI project for PeopleReady, and with cryptocurrencies seeing another bull run, I’m getting first looks at more than a couple interesting ideas,” Hopkins says. “I’m going to stay choosy with what I get involved in, but ultimately I just love playing with new tech.”
