Context
This was Sarawak's inaugural TEDx event, the first ever held in the state. The audience included government dignitaries, business leaders, and the general public. Most had never heard of Bitcoin in any meaningful context beyond news headlines about price speculation.
The challenge was to explain not just what Bitcoin is, but why it matters, particularly for communities where the banking system doesn't serve everyone equally. Sarawak, with its remote indigenous communities and limited banking infrastructure in rural areas, made this argument concrete rather than theoretical.
The Talk
The title ("The Cost of Cash") reframes the conversation away from Bitcoin's volatility and toward the hidden costs of the existing system. Cash has costs that most people never see: the cost of printing, transporting, securing, and replacing physical currency. The cost of being unbanked. The cost of remittance fees that eat into migrant workers' earnings.
The talk builds from these tangible, everyday costs toward the proposition that digital, decentralised money isn't speculative novelty, but infrastructure. An upgrade that serves the people most failed by the current financial system.
Significance
This was my first major public speaking engagement and it set the template for how I communicate complex technical infrastructure to non-technical audiences: starting from the problem they already feel, not the solution they haven't heard of.
The talk came during a period where I was simultaneously advising the Securities Commission Malaysia on their blockchain blueprint (Project Castor), running Neuroware through the Deloitte Top 50 RegTech programme, and building the Blockchain Embassy consortium. It represented the public-facing synthesis of all that work: making the case for blockchain infrastructure to the broadest possible audience.
