Is it worth imposing copyright on works (design)

Question

Freelance

I am engaged in design and a couple of times I saw how my work was stolen and passed off as their own. Now my level has become even higher and I would not want this to happen now.
Okay, I used to draw for myself, but now there are real projects that you spend time on and put your soul into.
Is it okay to put copyright on screenshots when showing work in a portfolio? I think the copyright is like on stocks, the transparency is 10 and applied as a pattern.
What do you think about it? Or spit and not waste time?!

Doesn't interfere with users at all, doesn't betray its presence, in case of disputes it can serve as proof.
After all, this is not a prototype, but a completed work for which you received money,
so there is nothing to be upset about. One can only pity those who pass off someone else's as their own.
Often, the difference between their own works and the stolen ones is immediately noticeable.
I myself have long adhered to the rule - just not interfering with the logo in some corner.

Answer 2

At your discretion, the main thing is not to tear your eyes out, and it does not interfere with evaluating the work.
