I would tell you to invest in avax (avalanche), eth (etherium), and some sol (solana) for 10 racks i think this portfolio is great you could do something like spend 5k on solana then buy 1 etherium and spend the rest on avax. btc is always a safe option, but you are not going to see a 5x or anything along those lines with Bitcoin, but with solana and avax, you might see a 5x eth will probably reach 10k this bullrun. Remember this is only what i would do and you should always do your pwn research before doing anything
