Sometimes it turns out that the fewer tools you have, the more you earn; the more you learn, the less you earn. In the face of the big trend, the simplest tools, including buying stocks outright and going long only with spot trading, far outperform learning to short or trading options for half a day.

In my view, the high-level operation that must be avoided is counter-trend shorting to catch volatility and end-date options. These two things are not inherently problematic, but they are essentially similar: trying to create volatility with leverage when there is no market movement.
Even the most skilled traders might stumble because of a "monster coin" like ethereum:0x17205fab260a7a6383a81452ce6315a39370db97, or because they mistakenly hold positions on other "monster coins" and make money, only to fall flat. Even if you correctly identify the direction of certain sectors like AI, semiconductors, or storage, due to the time cost of options, a single trade can go to zero immediately, because trying to show off with fancy operations often earns less than the simplest approach.
The essence of tools is to identify the right direction to amplify gains; fundamentally, it’s about going with the trend, not playing tricks in stagnant markets or even going against the trend. The great way is simplicity.
