Is it safe to provide CryptFolio a NiceHash API key?
At the time of writing, a NiceHash ReadOnly API key can only be used to retrieve account balances and worker status;
it should not be possible to perform transactions or change user details using the ReadOnly API key.
Your NiceHash API keys will never be displayed on the CryptFolio site, even if you have logged in.
Through the NiceHash interface you can generate new API keys by
visiting your Account page and clicking Get new key.
