What is supposed to be done during a bull run for long term holders?

I am fairly new to crypto, been doing a bunch of research for the past months and I started investing weekly into BTC and ETH. My main objective is to hold both of these cryptos and not sell for a long time. Since we are experiencing a bull run, and I don't have much experience in the matter, I am not sure if I should be blindly buying ever week for DCA purposes or if I should wait for BTC and ETH to drop low and then start buying again (In the meantime I would just stack the weekly money I would have put in these cryptos). I have read numerous threads here saying that if you are a long term holder, you should focus on just buying regardless of the price, and then there is the other side of people saying I should wait for the prices to drop and then buy (and yes, I have read the dropping knife analogy almost 30 times). This is causing so much turmoil and I am not sure what to do. The money I invest on a weekly basis is 10% of my investment portfolio that I wouldn't mind losing if things went left, but I obviously want to make the most intelligent move and would highly appreciate some guidance.
