New to Crypto, any tips or suggestions for investment?

Looking to put a bit of pocket change into different crypto currencies, specifically ones that are more on the cheaper side of things. I put about 20$ into Loopring, but pulled out right before it tripled in price. I’ve also put about 30$ into Shib, only because I saw dogecoin become relatively profitable due to the constant memes. Not hoping for much from SHIB, but anything counts.

So, would anyone be able to give me any tips regarding holding or what I should look for in a crypto?

Suggestions for crypto to invest in is also welcome, though again I would like to keep it on the lower end of things.
