You can play by yourself now. Just because there are no losses now doesn't mean there won't be in the future. Last year I followed someone, and he made four to five hundred thousand. But this year, with the Bitcoin crash, he directly lost more than two hundred thousand.

Dear experts, I am a newbie. I selected a few people to simulate copy trading in the public domain, some went bankrupt, some made profits, and some incurred losses. However, there is one who has surprisingly made a profit of 30% so far. Can I directly follow their trades?
