Step 2 Increased gold investment interest among 50s

Step 3 Inability to compare costs and risks across storage methods after buying gold

Step 4 Difficulty choosing between physical gold storage, gold bank accounts, and safe deposit boxes

Problem

When people in their 50s-60s who bought physical gold (gold bars, gold coins) due to the surge in gold prices decide on a storage method, there are 4-5 options—bank safe deposit boxes (200,000-500,000 KRW per year, approx. $150-$375), home safes (theft risk), KRX gold accounts (no storage fee but VAT on withdrawal), and private storage companies—but there is no place to compare annual costs, insurance, taxes, and risks at a glance. A wrong storage choice can lead to unnecessary costs of 500,000-1,000,000 KRW (approx. $375-$750) per year.

Solution

Enter the weight and type of gold you hold (gold bar/coin/KRX), and it provides a comparison table of annual total costs (storage fee + insurance + tax) by storage method (bank safe deposit box/home/KRX account/private storage). It also shows theft and loss risk ratings. Provides links to available bank safe deposit boxes by region.

Target: People in their 50s-60s who hold at least 100g of physical gold bars, and are beginner-to-intermediate gold investors lacking information on storage methods.

Revenue Model: Free comparison table. Detailed savings report PDF when switching storage methods: 5,000 KRW (approx. $3.75). Affiliate fees from banks and storage companies (lead-based).
