We are developing the free command line tool LibreSelery to pay salaries in the form of cryptocurrency to our developers. Since protontypes want to be a sustainable organization we want to offer an energy efficient alternative to Bitcoin in our default configuration. Since Bitcoin is supposed to be the most stable cryptocurrency, we decided to use it in the beginning, but now we want to change to something more energy friendly. Unfortunately I only have basic knowledge about cryptocurrencies. Our requirements are:
1. High currency stability
2. No fee for transaction between market wallets to allow microtransaction with LibreSelery
3. Traded on a crypto market with API access that does not require a commercial account.
4. The market must allow crypto to be sent to any email address without a commercial account.
5. The market must allow the complete transaction history to be obtained through the API for transparency.
6. Support in many countriesCurrently we are using the Coinbase API and are actually very satisfied. If it were not for the high energy consumption of Bitcoin. Here is a list of the supported cryptocurrencies: https://help.coinbase.com/en/coinbase/getting-started/general-crypto-education/supported-cryptocurrencies
Which cryptocurrency can you recommend based on the requirements? Do you know another market that we can offer as an alternative with more energy friendly cryptocurrencies?
