I think the best way is INVEST and HODL!
But it depends, you may want to learn to use crytos and some basics before...
One good way to start it through faucets, it's a micropayment system.
You need to create an account on a microwallet service
Link your crypto wallets to this account
Earn cryptos visiting websites, doing surveys and offerwalls, doing some referrals or even participating on some contests to earn cryptos without any investment required
You may start your own website "cryptorelated" and generate income (I did)
You'll start with small amount to know how it work and you can go bigger when you feel confident...
You can also meet a lot of people with more experience that can share some knoledge with you!
If you want to try this way I'll leave you a link so you can check it out!
