About

I help people secure their Bitcoin properly — hardware wallet setup, live and one-on-one, plus risk mitigation, safe buying practices, and inheritance/recovery planning, so it's secure and usable by you (or your family) when it matters. My background is economics, not code — so I explain Bitcoin in plain language, not developer-speak.
