What does it mean to download mobile phone mining software and mine at fixed points every day? Is it a scam?

Mobile downloading and mining software at fixed points every day means using mobile phones to mine virtual currencies, which is a scam. Mobile mining is to buy a mining machine to generate virtual currency, conduct internal transactions, etc. All peer-to-peer transactions are scams for novices. The first batch of people who play can make money, but those who enter after that are cut off from leeks. Don't trust mobile mining. Even if there is an internal trading platform, if the platform has made enough money, it will shut down the server and run away.
