As of the morning of April 8, 2018, the total market cap in cryptocurrency was $263 billion. Just 36 hours earlier, a bootstrapping and enterprising startup founder lamented his plight.

He wanted to invest in cryptocurrency, but it seemed difficult to get into. He was concerned about the risks and he didn't know anyone else who was investing.

The seed of an idea was born.


It's hard to get started with crypto investments.

  1. There's no safe way to do it.
  2. It's scary to do it alone.
  3. It's difficult to understand.

Built with

We built CoinCache with bcoin, Javascript, Node.JS, Swift, and Sketch.


The largest challenge we had was understanding bcoin and using it in our project.


A notable team accomplishment was utilizing our own computers to host the backend.


This team was comprised of the following individuals:

  • A UI/UX Designer learning to code in Swift
  • A Swift software engineer learning to design
  • Frontend engineers learning backend engineering

Suffice to say, everyone learned something new and received peer mentorship while working on this project.

Next Steps

We're planning to further build out a feature that allows socially conscious investors to donate a portion of their capital gains to vetted organizations. In addition, future versions of this app may allow investments in multiple cryptocurrencies.
