Spot trading is safer than Future trading. More people lose in futures than in spot trading. For beginners it is better to start with spot trading, that too by spending a little amount, and adding small amounts at every dip. Once they become experts in spot trading or at least, once they can handle spot trading , then they can learn future trading.
Those who are beginners in future trading, they should start with very very small amounts and with 2x leverage, and a tight stop loss.
When you are in crypto, keep it in mind it is about profit as well as loss. You cannot be at profit every time. However, losing big amounts in trade and getting liquidated isn't a very smart idea.
No one except a very few lucky people get rich overnight. Remember slow and steady wins the race. Spot is always safe and better option.
