From my own experienced, a few months ago, I already hit my target on Bitcoin and I sold some of my Bitcoins and altcoins.
But I still own some, it does not mean I will not buy again, it's because it's my technical analysis and since I am investing - I just took profit.
To answer your question based only my own opinion, I am still not buying for now.
Every investment must have a target, what you are doing is correct and after getting a profit from the investment you have made, there is no harm in trying again with a different plan.
Currently the price of Bitcoin is falling slowly, and if you want or have a plan to invest long term I think this is a very good time to enter/buy.
Currently I am trying to increase my assets, I am slowly buying when I have extra money that is not used, I predict that the price of Bitcoin in the future will be quite high so there is a possibility that there will be big profits that we can get.
