I'll go with ETH and SOL since both of these are my favourite altcoins. Bitcoin always stays at the top though.
FTM and BNB are also some nice coins I have my eye on but for the time being I am waiting for some fiat money to buy them.
I think we can also buy some Decentraland or SAND to stay invested in the metaverse.
Even though you have a list of many other altcoins to invest in, but you should allocate 30% to altcoins, and half to more Bitcoin, ETH and BNB. But I see a high drop for FTM, however I am interested in doing research whether it is worth and potential investment for the future.
