Are you a one-man team developing this website? If you are I don't think you can handle every topics your are putting in your website. Even if you say your niche is Bitcoin you are covering ablot of things from exchanges, ATMs, mining equipment, and news and I don't think one person can do it especially if you are thinking about how you will update it daily, your quality will obviously drop. Not unless you will be adding more members part of your team I don't think it will be a good idea to keep a crypto website to general like yours. I'm not saying that a one-stop shop kind of website is bad but what I'm saying is that it will be too much to handle just by one person.
