That's alot money, I think if you want to start investing you should know by now that you shouldn't invest all the money you have on all this  coins, you can keep a part of it maybe 25% for back up just incase the coins you invested in don't turn out as you expected, anyway if you still want to use the $16k,you can invest $4k in eth cause it's certainly going to hit $2000 very soon, the rest of them you can simply invest $2k each the likes of bnb, Chainlink, dot, inj,Ada, xrp, don't forget to DYOR before investing  .
