StackFi is market information for gold, silver and Bitcoin. It shows a live gold and silver price snapshot and offers six calculators: holding costs, gold-silver ratio, weight and purity conversion, token versus metal premiums, tokenized stock pricing and equity hedge basis. Research articles compare physical metal, ETFs and tokenized ownership.
The site covers tokenized gold (XAUT) as one ownership option but sells no tokens. Its guide is free and needs an email address. The page does not state pricing for the tools, so check the site for current terms.
People stacking gold, silver and Bitcoin were comparing prices without a clear view of ownership paths and holding costs. StackFi was built to make those trade-offs obvious before you buy.
