Now I have two Bitcoins and dozens of Ethereums. Do you think I should change them all to BNB for mining or keep them? If I change them all to BNB, which is about 700, the mining income is 400-500u per time, and 1200 to 1500u three times a month, which is a visible profit. If I don't change, I don't know when Bitcoin and Ethereum will go bullish. You are welcome to express your opinions. 🙏🏼
