What is your investment strategy? If you want to the long term profit, I will buy pundi X or hotochain, all they are listing in the Binance, if you want to short term profit, I will buy ETH, I think the price will hit higher in short time, then you can trade it and earn the money. 
I recommend ETH for long-term also; it remain top 2 cryptocurrency and I think BNB will be closer to it. It's good to buy pundix since the price now is low after the re-denomination and just like other's that commented OP should look for the tokens that he think will be good investment. Here my recommendation since you ask and you can make some research about it. ENJ since NFT are good investment today, THETA and INJ protocol. BNB is still a long way to go since it has quarterly burning event which trigger the price to increase and because of less circulating supply
