O 2000 dollar is big money, I hope you are doing a good investment. I would spread the money to different coins, maybe 10 different coins for 200$ each or 5 coins for 400$ each, diversification is alsways very good if a coin turns out to have a bad price.
Big coins are always very important to add because they are not likely to fail compared to smaller ones.

Here is my list:

BTC
ETH
EOS
waves
Monero
