Only bitcoin? Or mix?

Hey,

Until this day I only invested in bitcoin when it comes to crypto - I do have some ETH but let’s say 98% BTC

I have another 3,000$ I’d like to invest but this time I’m considering investing 50% in BTC and rest in Sol / ETH and I wanted to know what you guys think

Basically I consider other coins as shit coins that doesn’t solve any problem as BTC does but I became more open minded and I feel like I might be missing something
