$10 for each is too small and can you track all of them as one? IF you plan to go full crypto mode, you will not just put your money in one CEX or DEX but you will spread them among chains and wallets. Do you have bot or algo or software that track all of them? Such as notification, etc.
Your question sounds like a newbie's question, now there are many ways to track the holdings we have. So, keeping track of it all shouldn't be difficult. What's discussed in this topic is about the DCA method that's better for the @OP financial condition, so if you discuss anything outside of that it's irrelevant. I see you are advocating for $100 per project per week, that's not really the best way to do DCA (IMO), because we lose tracking for the other 9 at the beginning.
