I recently started to invest in BTC and bought from 4400 USD untill the recent prices $5000 USD up.
Definitely something will happen with the forks, Bitcoin Gold etc.
I am in for holding, but my profit is really fragile.
What are your plans for/ after 25 Oct? Dumps are expected. Is it an idea to sell before this date and buy back later?
What do you mean by "fragile"? You're green to the tune of 15% to 30% in a very short time. If you think it's in jeopardy and you can't afford to lose it, then sell it and take your profit. Don't expect anyone in here to tell you what will happen with Bitcoin with any certainty; nobody knows for sure... except maybe Jamie Dimon - he's pretty sure it's a crock.
