Is it worth investing $10 into crypto a week?

I'm doing research into DCA and think i'm along the right lines. I don't want to put huge amounts in yet as I'm still sort of finding my feet. Tempted to just flat out put $10 a week into ETH or BTC, or maybe up it to $20 and do 10 in one of those and 10 into (well researched) altcoins. What kind of strategy do you guys think is best?

edit: I should clarify I have stable income and am already signed up to three exchanges, already have some Altcoins etc from 2018 which I've come back to after losing interest from the crash. Deciding to give it another go now I have a stable income.
