If you want to trade futures then you need to adopt enough strategy to earn good profit from it. If you don't know the strategy, then you will not be successful immediately, so you have to learn the strategy later in trading. You don't need to have enough funds to start trading, just start with some money. But if you never trade in low marketcap tokens they will definitely have the potential to lose money. That's why you need to trade in good coins so that you can make profit.
Future trading is very risky for a trader, so if a trader does not have enough knowledge about trading, it is better not to do future trading. Futures trading is often compared to gambling. As in gambling, money either comes or goes, same is the case with futures trading. In future trading, if you can trade by understanding the market and taking risks and if the market increases or decreases according to your plan, you can profit, but when the price of certain coins increases or decreases outside of your plan, your chances of losing money increase several times. Futures trading is never the right decision for a trader without adequate trading skills. After developing sufficient trading skills a trader should decide to take up futures trading.
