The key is to Have proper risk management. Common mistakes that a lot of traders are doing is to simply go "all in" like they are playing poker. Do not use more than 5-10% for each position so you will not get rekt at your first trade. Don't risk 30% to earn 5%.
It's because those traders think about their profit first than the risks it have. They tend to all in hoping a positive result and when they get rekt they already lose all their capital. They don't know how to recover it because of their greediness. They will just hodl it until their capital is 25% to the actual amount they started.
