What are some great coins to invest in this bull run?

Hello,

As a beginner in crypto, I'm looking to diversify my investment portfolio by allocating around 1/4 of my spare cash into cryptocurrency. However, I'm feeling a bit overwhelmed by the abundance of information available everywhere at the moment.

Currently, I hold some BTC, ETH, SOL, LINK, AVAX, DOT, MATIC, THETA, VET and ADA since the last peak I bought in (in 2022, buying high). However, it's just a couple of thousand euros spread somewhat evenly (SOL is the only coin that has gone up since).

I'm wondering if there are any other cryptocurrencies I should consider purchasing, or if I should allocate more funds into some of the cryptocurrencies I already hold or sell some to re-alocate funds.

What would you recommend for a beginner like me? I'm using Binance.

Thank you.
