I'd say now would be a good time to have a foothold in both crypto and fiat. It is perfectly possible that Bitcoin shoots up several more thousands of dollars so you'd be in a good position with your crypto. However, I don't trust the steep current rise of Bitcoin in the sense that it is 'too fast' and the chances of a significant correction are higher. In that case, you would be able to make a move with your available fiat.
How do you see the relevance of the 1st Nov protocol change and potential fork? Do you think it has the potential to drive the market down like 1st of Aug?
I am doing exactly what you write, I still keep a very significant amount in crypto but today I decided to sell 10% of the portfolio to start accumulating cash. If bitcoin shoots some few thousand dollars higher I obviously will have lost on some profits but would still be happy to see that happen.
I think the potential November fork could be amazing for Bitcoin. The market did not get driven down August 1st, it started going up after. lol
