Have you checked leader board before on any exchange that are showing it to derivative traders? If you check it, you will notice that you can be able to see the percentage of ROI of each traders on the leader board. If you calculate it with the the difference of the entry price and mark price of the asset they are trading, you will notice that most leader board traders use 1x leverage. They prefer to use high amount of money but with no leverage or not even using all their money on their trading account, which can be know if they use crosss margin mode, you can not know that with isolated margin mode.
But as a beginner, use less than the amount of money you can afford to trade with.
As a good trader, use the amount of money you can afford to lose to trade.
If you should increase you trading fund, that means you have more success rate in trading position opened. If not, still always use the amount of money you can afford to lose to trade.
For bitcoin, 5x is getting high for me, but I can use it in if the market has gone very low, I prefer 3x for bitcoin. I prefer 2x for altcoins if I know the market will favour me when the market have gone very low, but I like 1x overall.
Good traders which are professional enough do not want to be fighting with emotion, that is why the prefer to open 1x or leverage, if they are losing, they still believe the market will correct itself either in short or long term. That is why you will see them losing but not closing position, but it is not a surprise anymore that the position opens that you thought they are losing would later favour them and they will gain massively.
But for those that just leverage, the greed has been what is causing them problem and liquidation which is the regret that they have.
What traders need most to first know are risk management and strategies, then followed by how to make analyses, starting from knowing about charts and indicators.
When You see market is in bull season you may buy some 3× or 5× Leveraged Tokens that will give you high returns
If you are talking about bitcoin, your post is good and I would have given you one merit, but altcoins are dangerous with 5x, it can result to liquidation.
