DollarTrader

ClaudeCommunityby DollarTader

DollarTrader gives agents two things. First, a weekly, issuer-sourced dataset of coins held and coins per share for all 22 US-listed crypto ETFs, ETPs and treasury companies — IBIT, FBTC, GBTC, ETHA, GSOL, XRPZ, MSTR and the rest — with the as-of date, data-quality flag and exact source URL on every row, so answers can be cited. Second, three calculators ported from dollar-trader.com: a Social Security break-even model (claim early vs. delay, with COLA, an invest-the-checks scenario and a surviving-spouse view), US CPI purchasing-power conversion for any two years 1913–2024, and ETF expense-ratio fee drag. No key, no rate card; data is CC BY 4.0. Educational, not financial advice.
