Trading bitcoins would probably get you more profit if you know what you are doing and don't have mining equipment.
Mining isn't very profitable anymore unless you buy equipment, etc. Trading would be better if you don't want to purchase a miner, but trading also takes quite a lot of skill.
Yes, the trade has an advantage for those who can trade properly ...!!. But sometimes a lot of people who haven't been able to trade well so they get is just a small profit, please note that trading bitcoin it is only temporary and cannot do anything good in a long time. To be able to benefit in trading better buy a lot of bitcoin when prices are low and keep it until the price is high, after it was sold.
