Ask Doctor Bitcoin: A Quick Crypto FAQ.

For those who don’t know, I’m a cryptocurrency fan. I’ve been following all of this very closely since 2011, and I enjoy learning more technical details around blockchain as well as theorizing and architecting new solutions utilizing blockchain. I also sell cryptocurrency through my company, Roger Wilco. As such, this week perhaps more than most others, […]

Ask Doctor Bitcoin: What does a Trump Administration mean for Bitcoin?

If you’re an American, last week was really weird. Without a doubt, most folks had reconciled with the fact that we’d have America’s first female president, only to have the apple-cart upset at the eleventh hour. We’re now ushering in the age of Trump, and that means a great deal of un-imagined consequences and uncertainty, which […]

Ask Dr. Bitcoin: What is Dollar Cost Averaging?

The typical cryptocurrency enthusiast goes through a few steps as they continue their journey, particularly if they see any early gains with their crypto investments. Initially, they’ll put in some sum of money – usually small – into a cryptocurrency and see some amount of gains and get excited. They’ll either be excited by the gains themselves, […]

Dell’s move to Bitcoin reflects their philosophical core.

Maybe I nicked this statement from someone, or maybe I come up with it, but a phrase I use a lot when I talk to people about Digital Autonomous Organizations is “.. the economy and the state are engineering problems, not political ones.” What struck me from the Dell announcement around Bitcoin acceptance is this is reflective […]

Ask Dr. Bitcoin: Is Bitcoin Anonymous?

Whether or not there’s a place for banking as we know it in the world of cryptocurency is a hotly debated question among Bitcoin enthusiasts and stakeholders. “Unbank yourself,” and “Time for plan ฿,” are many of the slogans thrown about the Bitcoin world, symptoms of the sub-cultures ingrained abrasiveness to traditional banking.
