Actually, you can choose whether you need to spend BTC for payment of any goods, changing it into the bitcoin ATM, or selling it in certain exchanges. if it is about the use and utility of BTC and its ATM, you can use COinradar or LocalBitcoins to check the status. And if you need to sell, try to know whether there is a local exchanger or not. Or you can use a global exchange such as Binance, Kraken, and coinbase.
