If you’re selling BTC to pay bills, you’re not really benefiting from ‘cheaper-ness’, you’re just spending your BTC and triggering a taxable event in the process. The whole idea of Bitcoin is not constantly converting it to fiat to navigate a system Bitcoin was meant to replace. In this case, you’re simply exposing yourself to unnecessary tax friction without any real gain over just spending in dollars for bills you know are coming. Again because with this feature you are not spending Bitcoin, you are SELLING it.
