I agree with the OP that these are some of the best data sources for Bitcoin enthusiasts and traders. I personally use CoinMarketCap and CoinCodex for getting a quick overview of the market and tracking my portfolio. I also find Datarade useful for finding niche and high-quality data providers that offer more insights and signals than the average sources. Cointelegraph is my go-to site for staying updated with the news and events that affect the crypto industry. I think these are essential tools for anyone who wants to succeed in the Bitcoin space.
I’ll admit that I haven’t dug into the sources mentioned here but it sounds like the only metrics available are price, volume, OI, and hash rate. Hash rate is the only one of those that resembles an underlying fundamental that I can try to use to project into the future. I would still like data on the number of new wallets created monthly and the number of businesses starting to accept BTC as payment. NASS has all sorts of non-price data for commodities that is collected from mandatory reporting by businesses and producer/user surveys. I want to be one of the first to utilize this data when it’s available.
