I do agree with you. It is really fascinating to see Bitcoin's value continuously increasing. It surpassed the 5000-dollar mark and aiming for a higher price before this year end. Surely, huge profit will be to its user and investors if its value will be more expensive if the next hardfork in November will be successful. Holding at this moment is really necessary.
Indeed bitcoin is really unpredictable and good things now are happening to those who patiently wait for this. And some are really converting some of their bitcoin to fiat to somehow taste the moon and I think it's okay and just keep some decent amount for the upcoming hardfork so we can get bitcoin gold.
Why do you need the bitcoin gold? It is only in the beginning of his career so it will be a long time to gain the price. If you sell your bitcoins when the price will be high because everyone wants to get free bitcoin gold. Then you can buy more bitcoin gold and buy back the same amount of bitcoins.
And from all the look of things, I could not believe there can be someone who would think bitcoin gold will ever catch up with the value of bitcoin. It apparently will have the same fate as BCC or even worst. It might have a chance in the market and serve a purpose, after all some shitcoins do, but being able to catch up with bitcoin would be anyone's wildest dreams.
