Coinwarz: The Ultimate Crypto Calculator Ranking Tool
Coinwarz provides information on the profitability of Bitcoin and other cryptocurrencies through calculators for various mining rigs. The site may be technical and confusing for newcomers, but still interesting to use. It has a list of cryptocurrencies and their mining data, comparing altcoins to Bitcoin. However, profitability is subjective and can vary from reality as it doesn't factor in fees, exchange rates, pool efficiency, or difficulty.
