Doge is the only real choice.

Simple math and odds,
is the odds better that Doge increases to $1  ( a 2000X increase )
or
more likely that Bitcoin increases to $100000000  ( a 2000X increase )

The little guys and 3rd worlders are done with BTC , doge is the only real game left, as it has become the major trading pair for all altcoins below $1.

But you have enough you can split between multiple coins and hedge your bets.
Pick 5 coins, you like and place 2k on each, that way all of your eggs are not in one basket.
Good Luck in your Choices.
