There are many clueless individuals in the square teaching others to roll over, while they themselves roll as much as they can. I roll you to f*** off, if you want to die, don’t drag others to accompany you in your demise. Increasing positions for profit may be practical in other industries (like futures, spot gold, forex, etc.), but in the cryptocurrency world, you absolutely cannot do this. There is a rule invented by someone who is cut off from future generations, known as the liquidation fee. In other industries, once your margin is insufficient, the system will start liquidating from your largest losing position until your margin meets the requirements (if you have only one position, it will be liquidated and the remaining funds after losses will be returned to you). The loss amount is the loss points multiplied by the position size; the loss is exactly what it amounts to. However, in the cryptocurrency world, it is not like this. If you increase your position using high leverage for profit (what is called rolling over in the crypto world), if the market moves slightly against you, even if your position is actually profitable, you could still face liquidation. Liquidation in other industries might mean losing part of your margin, but in the cryptocurrency world, liquidation is very terrifying; it means your account is directly being actively robbed. In the square, you can see many altcoins liquidating in 1 second or even 0 seconds; for example, if you have $100 and you put 75x leverage on some altcoin, you might only need to lose $10 to get liquidated, and the remaining $90 will be actively taken. I advise everyone to absolutely avoid using high leverage for contracts, especially with altcoins, and definitely do not listen to those who tell you to roll over.
