I think mining needed to invest in hardware and software to solve complex mathematical problems that validate transactions on a blockchain network. As you mine, you will rewarded with newly minted cryptocurrency.

on the otherhand, buying cryptocurrency in a bear market can be an option. as prices are generally lower than during bull market. But there will be a risk that is no guarantee that prices will rebound. you will keep losing money if the price continues to fall.

but i don't think mining is dead, the decision to mine or buy crypto in a bear market will depend on the circumstances and risk tolerance.
