What is more profitable, Crypto mining or trading?

There is much more volatility in trading than mining, however, both are subject to the volatility of the market. If you mine Cryptocurrency A, and the value of it drops, and you are holding that crypto, then you will lose out on money. On the other hand, if you are trading with Cryptocurrency A, and price drops by 10% you have the ability and control to immediately sell the coins and minimize losses.

Mining has a lesser chance of multiplicative gains, but also has a much lower chance of losing everything (i.e., less volatility/risk). A miner would need a hardware failure in order to lose absolutely everything

With mining, one has an initial investment that one has to recoup indirectly - you buy the mining rig (usually one buys the parts and then builds the mining rig), use it to mine crypto, then have to make an informed decision of when to sell your mined crypto on the marketplace, to recoup your investment and take profits.

With trading, one’s initial investment is what one is risking. It is a more volatile situation, with higher risks, which means higher rewards as well.

Trading has a much smaller entry barrier than mining, and one may start trading with as little as $100. A dealer’s trading balance can be increased over time as they develop knowledge and expertise.
