Why not do DCA? In what way do you think that strategy wasn't helpful to you?

I have been in the financial markets for almost 4 years trading futures and spot and I lost 50 thousand dollars, I would not do these things again:

1 - No Overleveraging
2 - Do not DCA in your trade
3 - Never use money that is not mine

I have an extensive list of mistakes made, if you are interested in me continuing with this thread of posts let me know in the comments
