That was the case that copy-trading is not a good idea if we are building ourselves to have a better future. And these traders who allow being copied by someone will certainly don't mind as they know they are not working well. And besides, I don't believe those influencers who want to help others and teach their strategy because successful traders will just share their experience, not their working strategies as they are too clever enough to hide secrets of their success.
Some traders were taking it too seriously as most of the exchange who have such features probably are paid traders or have a goal to be on the top of the list in that exchange. Though it will still depend if we’re lucky enough to copy a trader who is into that goal since others might not be serious always that’s why it will be better to still have knowledge on it than to rely on somebody else unless we believe too much in the person we copy trade.
