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)
Link, one viz: https://blockviz.xyz/price/daily-returns and one simulation: https://blockviz.xyz/simulation/coin-flip
Happy to answer questions about implementation, data sources, or design decisions. Critical feedback very welcome.
