it is very important to be most careful while day trading when volatility is high, just as it has been in a few days now, this is specially for those who trade the futures market, trading futures is 10x more risky than trading spot, in futures trading, a simple miscalculation or failure to use proper risk management could lead to you being liquidated and all the money invested gone in a twinkle of an eye.
Future trading is not something you should just start easily, your chances of losing money when it comes to future trading are higher. I don't recommend anyone to go into future trading, and if you will be going into it, always make sure you are using small leverage with a small amount of money. Don't be desperate to make big money, or you will end up losing everything you are having. I know some people are pushed to trade futures because of the high reward that's there, but if you are not careful, you might end up losing everything.
I am sharing this based on a story a friend of mine told me yesterday about how he lost crypto NetWorth in just one trade on one faithful day way back last upper year which is 2022. According to him, he went long with all of his entire crypto NetWorth on an Altcoin because he was expecting the price of the altcoin to jump back up, after a news (which was later confirmed to be fake) caused the cryptocurrency to go down, but unfortunately for him, by the time he woke up from sleep the next day, on checking on this trade, he discovered that he had been completely liquidated because the price of the crypto currency ended up dumping even harder than before.
Your friend is funny, i guess he was trying to make use of opportunity to make big money. Your friend is supposed to know about risk management, why will he decide to use his entire crypto net worth on a trade? It doesn't make any sense to me. No matter the news which I hear, I can't use all my money to trade on future. I once wasted money on future trading when I was learning how to trade, since then I don't even go close to future trading. When trading, always make sure you use a small percentage of your money. In case something goes wrong, you will always have backup, and always maintain small leverage.
