I need an objective opinion

I am about to start investing, but should I wait to buy the dip or DCA from now on?

I wanna start a Portfolio with: BTC,ETH,SOL and some XRP or Cardano (starting with small amounts for some years, i am still a student).

I dont need the hype guys who say “yea +2000% tomorrow” etc. but something that enlights me!

Would be really really thankful!
