Spot trading is the best choice because you won't be liquid when your prediction is wrong, you just have to be patient to wait for your coins to rise again, but you can also try selling them when you lose and buy them again when the price falls even further.
It's just that both have their own risks, the most effective way is for you to have experience in both.
You're right! Both spot and future trading involve risk and there's a need to have a strategy in place to manage that risk. In fact, the first thing to keep in mind when it comes to trading is risk management. Generally speaking, spot trading is recommended for beginners as far as trading is concerned. Future trading can be more complex and require a greater understanding of the markets and this will make it more difficult for the beginners to grab. Future trading can be more risky despite that, it can also offer the potential for greater profits and spot trading is less risky but it can also be less profitable. However, in my opinion, I think it's better to earn slowly through spot trading than to try to earn big with future trading that you might probably lose everything. It's widely said that slow and steady win the race.
