Here are the top three coins that will make money after the next bitcoin halving:

1. Ethereum (ETH): Ethereum is the second most popular cryptocurrency after Bitcoin. It's not just a digital currency; it is also a platform for smart contracts, which are like digital agreements that automatically execute when certain conditions are met. Ethereum is planning an update called Proof-of-Stake (PoS) that should make it faster and more efficient. This update could push more people to use Ethereum, which could lead to an increase in its price.

2. Binance Coin (BNB): Binance Coin is used on the Binance exchange, which is one of the largest and most used cryptocurrency exchanges in the world. You can use BNB to pay for trading fees and other things like travel bookings. When a Bitcoin halving happens, usually more people start trading cryptocurrencies, which can mean more people use Binance and buy BNB, which can drive up its price.

3. Solana (SOL): Solana is a new blockchain platform that is designed to be very fast and efficient. Recently, it has become more and more popular and is now among the top ten cryptocurrencies.
