What wallet and Defi apps do you recommend?

I’m a college student that doesn’t have much to invest but I might save up a bit every now and then. I used to use Metamask and Pancake swap for the shitcoin season when Shiba was the thing. Right now, most of my money is in CEX like crypto.com or revolut but I would like to move it to my wallet and stake it in DEX. I won’t be needing money soon so I really just want to have somewhere to stake BTC and ETH and have some alts like CRO and DOT and add little money to them every week/month. Revolut seems very comfortable and user-friendly for doing little DCA but I don’t like their staking system and I’d rather have it in my personal wallet. As you can probably tell, YES I am still confused with concepts and stuff so any guidance / recommendation / advice would be very helpful. I just want the little money I can save up now to be a bit more useful in a future. (also maybe have the opportunity to gamble like $20 in a shitcoin when the time seems right)
