i always say to new people its best to look into Defi ( Decentralized finance ) as this is where all the major smart money is setting up in,
https://defipulse.com/ is a great site that will show you all the current / popular defi projects, i use swyftx to buy my crypto and i store it in exodus wallet , i would never keep crypto on a exchange.
i try to help everyone in this crypto sector but there is so much info to go over man u would honestly find my previous post's useful if you want to get started, so just Lurk through the recent post's on here.
as for projects with big upside , i own a huge chunk of projects i believe in, And some have blessed me & some still in great growth cycles, others ive ended up turning the Profits into bitcoin, its important u dont fall in love with a project too much, The goal is to accumulate satoshi's ( bitcoin ) as it seems Bitcoin is going to be the place when it comes to Storing value.
Chainlink Vechain ZIL REN ADA DIGI litecoin Compound UNI
Like i said though, There are just too many to list honestly, The ones i listed above just seem to be super under valued still and Look to have have plenty of room to grow
