Now that you're on Binance Smart Chain (BSC), you'll need to fund your wallet. You can do that by purchasing BSC's native token BNB on an exchange like crypto.com, Binance, or any other exchange that allows withdrawal to Binance Smart Chain (BSC). Just be sure it's BEP-20, and not BEP-2.
If you already have crypto on another network that you'd like to use on Binance Smart Chain (BSC) to invest in EMP Money, you can also just bridge those funds over!
