Hi HN,

I’ve been building a crypto market & portfolio visualization site in my spare time and wanted to share it here to get honest feedback.

The focus is on visual explanations and “what-if” scenarios rather than price charts only. For example:

• indexed performance comparisons (e.g. BTC vs ETH over arbitrary ranges)

• market cap & dominance breakdowns

• what if you held or missed the best trading days

• portfolio tracking with cost basis

• simple strategy simulators (HODL vs DCA, sell & buy back, coin flip)

The site is free right now. I’m mainly trying to understand: - which parts are genuinely useful vs noise

- what feels confusing or unnecessary

- what you’d personally want next (or would never use)

Happy to answer questions about implementation, data sources, or design decisions. Critical feedback very welcome.
