Hi@Baroona, thank you for answering.
I think it is me who is dumb tbh.

I have been tying myself up in knots over nothing, I have decided.
Because if I sold 10.000 shares at $2.00 each, the average price of the remaining shares, simply must remain the same.
As it has no effect on the original price.

If I top up again, the average price is automatically adjusted by the broker.

Funnily a lot of people have got confused about this, as I looked at another site, where people were asking the same question.

So now I have it all clear in my mind, I have nothing to worry about.
Thank you for trying to help
