It would not be a wiser decision to invest all $ 16000. It's your savings and I think you are not an old customer in this market. Because of the characteristic of this unstable market, I am suggesting you make investments all your balance. Your mentioned all coins have good potentiality. You can invest 50% now, make a profit then invest the profit as well but keep something for you now. You can go with the other 2 except ETH because the price is already high, this is not a good time to invest in ETH for a new one with a limited balance. Hope you understand what I am trying to say.
