Before you mine crypto, it is necessary to calculate the cost of mining, especially electricity, whether electricity rates in your country are expensive. If it's expensive, you better not have to think about mining Bitcoins. But if the tariff in your country is cheap, you need to have the latest mining hardware, you also need software, and other devices. Join a trusted mining pool like Poolin, Antpool etc. You will only waste time if you join cloud ming that is never profitable.
