After calculating the contract fees, 10,000, with 20x leverage, that's 200,000. Each time I enter with 20,000, the fee is 0.15%, which is 10 units of oil. Each trade incurs a fee of 20 units of oil. The fluctuation of the asset is one-thousandth; if I short it and the asset drops 100-120 units of oil, I won't lose money (the asset price is changing, and this also changes; that's the algorithm). I have a habit that as long as I have the right direction and I'm in the profit zone, I will calculate the fees and move the stop-loss to breakeven. Anyway, if you rebound, I won’t lose money; if you go higher, I will continue to open positions.

Going long is the same.

If I lose money, I will wait for the stop-loss to trigger.

The spot trading fee is 0.1%, so buying and selling is 0.2%. Generally, I hold onto spot positions and don't move them, waiting for months. For short-term trading, I may have 1-3 trades a day, but contracts are different; I can open them at any time, but I shouldn't open too many, as it can be exhausting. Unlike spot trading where you wait for lower points, both long and short can be opened here, and it feels like you can make money anytime; actually, that's wrong. It should be said that losing money is easier; you can lose money anytime, whether long or short.

In spot trading, there's not much difference between the asset prices at 75,000 and 75,100 or 74,000, so I generally only look at the thousand or hundred marks. Now, doing contract practice, I look at the points at the ten and unit levels; if I look less at 100 units of oil, that’s the fee! If I look less at 1,000 units of oil, that’s a 20% point! (I opened at 20x leverage; I've tried 50x and 100x, but they are too uncontrollable!) Doing a contract really requires pushing myself to see the points accurately. I estimate that I can practice that; I'm not planning to practice after the second decimal point.

Next, I'll do some 1-hour and 4-hour levels. If there are sudden events or data releases, I’ll take a small bite. Higher levels can be held longer; they are not so frequent, and I can study and analyze the market calmly and sleep well.

The asset's direction is still upwards; Ethereum is also going up, stronger than the asset, so I’m not looking to short for now. I short when I hit the point; the smaller levels below the asset are at 108,670, 108,291, going deeper to 106,986, 106,707, 105,321.

Mainly, the ETF is too aggressive, combined with the buying from MicroStrategy and listed companies. The market makers also dare not push hard; if they push down, they can't get on board, so how can they manipulate and harvest retail investors?

Previously, the BTC supply on exchanges was over 3 million; today, I checked the data and it's only about 2 million now. China has 190,000 coins (I'm not sure if this data is accurate; it needs to be verified).
