I was shopping for a home miner and was trying to compare hashrate vs. energy cost so I built this calculator. There some miner examples to choose from but you can also do simulations with your own custom values. Feedback is appreciated ✌️ https://sugiro.io/hash/

I’ve watched others from Simon so I’m still preparing myself psychologically for this one - I know it turns your stomach. Having said that definitely a must watch.

BTW if you're looking for BTC - CAD here a great calculator https://mempool.space/tools/calculator
Scroll down and you'll see there is a FIAT menu

Just updated this Bitcoin Calculator to include Euros and GBP (if you've been using give it a hard refresh please).
A few notes:
- There is an API to fetch the prices from Binance.
- If you're using BRAVE you might see an "error fetching price" message on the calculator dashboard because of BRAVE's default security settings.
- Also, I tried to add CAD (Canadian Dollars) but apparently Binance is no longer operating in Canada due to regulatory issues so they are not serving a BTCCAD pair - Sorry Canadian friends 😟 BUT if someone has a suggestion for how to workaround this I appreciate (maybe a better free source for fetching BTC, USDT and Fiat pairs would be great).
Feedback is always welcomed !!!! ✌️ 🫡

I can’t tell is a suspicious site issue because I turned off “Block Dangerous Websites” in Bravee’s settings >shilds &privacy and it worked.
Now I’m looking into it. Seems like the best approach will be to set up a proxy server for the current price avoiding a third party api call. Hoping to fix this soon. Many thanks for the feedback 🤝

Naming is fundamental to usability. If you give something a
