Why Passive Income Matters

I run Mars Money Lab to test real passive income and growth ideas — from matched betting and rewards cards to long-term stocks, crypto DCA (Bitcoin/Ethereum), and AI/tech plays — and show the actual numbers with no fluff or fake results. Every pound you see comes from my ongoing experiments above (more on the full dashboard).

Koinly — Automatically tracks every Plutus reward and crypto trade for easy tax reports.

Proton — Private email + password manager so none of my financial logins or statements ever leak.
