Problem

As gold prices recover to $5,200, individual gold investors are surging, but channels such as bank gold passbooks, the KRX gold market, gold bars, and gold ETFs each have different fee, spread, and tax structures, causing investors to spend an average of 2-3 hours comparing optimal channels. In particular, fee differences can reach hundreds of thousands of KRW depending on buy/sell timing, but there is no tool to compare them in real time, leading to unnecessary costs from trading on suboptimal channels.

Solution

A service that compares real-time buy/sell prices, fees, and taxes of bank gold passbooks (5 major banks), the KRX gold market, major gold dealers, and gold ETFs on one screen, and simulates net returns by channel when users input investment amount and holding period. Differentiated by providing price alerts and a monthly fee savings report.

Target: Individual gold investors in their 30s-50s, office workers and self-employed individuals interested in asset management with investment assets ranging from 10,000,000 to 500,000,000 KRW (approx. $7,500 to $375,000).
Revenue Model: Premium SaaS 29,000 KRW (approx. $21.75) per month per account (real-time alerts + simulation), free tier limited to 3 queries per day. 20% discount for annual payment.
