As a young investors you don't need a million dollar before you investing I Bitcoin, you can start by investing $200,$300,$500 everyday for 2 or 3 years, and you'll be a millionaire, and I know today that is how most people start up there Bitcoin investment journey and today they are millionaires, so that is also a way for the young investors to start their investment journey, thank you.
In my opinion for any investor who wants to collect bitcoins, you don't need to focus on $200/day, investing whatever amount you can afford, whether consistently every day, every week, or every month doesn't matter because longterm investment methods like this still apply. If you suggest putting in $200/$300/$500 every day then what about those who can only afford $10-$100 per week should they postpone their bitcoin investment?
I prefer to let them define the DCA method in a way that can be done. As long as the money invested is truly aimed at the long term.
