Does playing currency rely on luck or algorithms?

In every bull market of btc,

At least two corrections above 50%;

20%-30% correction at least 10 times;

There have been dozens of corrections of around 10%.

Among them, more than 20% of the corrections are called risks, because more than 4 times the leverage will be liquidated.

Therefore, if players with a leverage of more than 5 times want to roll positions, they will basically miss the bull market; if they want to take both long and short positions during the trend, the risk will double again. Those short-term players with leverage of more than 10 times are no different from going to Macau.

It's not a question of risk preference, but of being unable to defeat the Kelly formula.
