Coinstate
Hey HN, Last month, I wanted to buy some Bitcoin and noticed something strange: the price was different on every exchange. Unlike the stock market, crypto doesn’t have one official price. I tried using CoinMarketCap and other sites to compare prices, but they didn’t really help. So, I built Coinstate a simple, free tool that lets you see and compare live crypto prices from many exchanges in one place. It currently pulls data from Binance, Coinbase, Kraken, OKX, KuCoin, HTX, Bybit, and Gate.io, with Crypto.com and Gemini coming soon. You can filter by trading pair, sort by price, and see near…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years.
