Buying and holding

After years of being skeptical about crypto and not having the luxury to invest, I decided that it is time to start doing so with my financial situation improving. I decided to just put a 100$ 2 days ago before the elections on crypto.com as an experience and also hands on seeing how things work and fluctuate. I put 40$ on btc, 30$ on eth, 15$ on sol, 10$ on polkadot, 5$ on cardano. Being a beginner with crypto, what recommendations you’d give me about my split between the coins, what to keep my eye on and what to target next. Noting that I am not super interested in short term, I am more wanting to buy and hold. Thank you and I appreciate all the help for a new fellow.
