Cryptocurrency: Personal Finance Management with Coinbase API and Open-Source Google Spreadsheet and Script

Most media and some experts see cryptocurrency struggling. Some say bitcoin and blockchain are overhyped or even locate crypto-exchanges in the trough of disillusionment. As s visionary and strategist, you know this may just be the right time to invest: As we’ve cycled about two-thirds of Gartner Hype Cycle, the plateau of productivity is almost graspable, limiting volatility.

Examples include loan and rental agreements or corporate bonds. With Blockchain’s built-in peer supervision, central authorities and even notaries may become redundant. This yields a huge opportunity for developers, startup-companies and investors.

Efficiently Building MVPs for Lean Startups

» Ideas Are Easy, Implementation Is Hard « – Guy Kawasaki

I have met numerous entrepreneurs, startup teams and companies with brilliant ideas and strong visions. Creativity, knowledge and multidisciplinary teams foster disruptive ideas.

Implementing disruptive ideas is a complex problem, though. When it comes to complex problems, the relationship between cause and effect, by definition, is not clear. In order to figure out, if an idea is truely a great idea, we have to try it out!

Validated Learning

Both, the lean startup methology and the validated learning process, provide a proven approach for quick and early idea validation. Not until we performed some early testing, could we rank and compare multiple ideas and paths.
