Taking profits

Hey all, I was hoping to get some advice and opinions on taking profits. I unfortunately started buying right around the all time highs of the market, and then had some financial issues so I was unable to DCA for a while. Luckily this worked out in my favour and I missed buying almost the entire fall back to the bottom and was able to average down to the extent that I'm in profits now.

My original plan was just to sell half of each of my holdings when I hit 100% profits and then sell a quarter at every 50% increase from there, while buying the dips with my profits. I plan to hold as long as I need too and these dips don't bother me at all, but I am wondering if waiting for 100% profit before selling is being a little greedy. For example I was up over 50% on MATIC not too long ago and am now back at 2% profits.

What do you all do? DCA out at smaller intervals or just hold until the halving? Thanks in advance for your suggestions!
