Can someone explain to me in laymans terms the expected future of ETH?

Currently I buy $50 a week into ETH, but since the price of ETH is so consistent it seems profiting isn't really that great, I know it's an investment, but why would you tell someone to buy ETH over BTC? Keep in mind, I know almost virtually nothing about Crypto, I just blindly buy because I've been told by many people to invest in ETH because "it's gonna be the future."

Why is it the future?

What is the difference between the two? #EtheruemETF
