So one of my company's products shows data based on market depth as opposed to market cap. I figured that this board is the perfect one to ask this question...



I'm used to always seeing Bitcoin at the top of charts based on its market cap, but this site shows Ethereum ranked at the top based on its Buy Pressure. Honestly, I'm embarrassed to ask my colleagues (I'm not in the same product department as the one this site is in), but can someone ELI5 (explain like I'm 5) in layman's terms why market depth is more important than market cap when it comes to trading?

Thanks in advance! I'm looking to get more knowledge in trading crypto, so you'll start to see a lot more of me on this board. Cheers!

(Let me know if I should move this to Beginners & Help)
