Question Regarding WD from Binance

[Hemoglobin]

I am new to all this. I have a simple question.

I have invested in some coins on Binance.

Let's say that those coins go up to $1000 ea and I want to cash out.

The coin is on the Eth network.

From what I gather, I would sell it all on the Eth market and then WD the Eth to my wallet.

So, what if Eth drops down to $100 while this other coin is $1000+?

Do we rely on Eth staying higher or what?

Thanks for filling me in on this.
