Thanks for the idea about the popup subscription. I hate popup on any site...I would like to keep the site clean. However, I do hav that free bitcoin ebook download, which a lot of people have downloaded so far. You have to enter email to download.
No offence, but I've always been under the assumption that if you create a service that brings nothing to the table or doesn't fix any issues, there's no need for the service and it'll eventually get pushed out of the market.
I think this is what your project looks like right now, I don't see anything better than the other 2 established projects, it would look better than the other 2 sites but there's a huge ad in the middle that I'm unsure how to close.
I guess good luck, try to bring something new to the market and I think you'll have a lot more success.
You have a good point in fact there are a lot of ready script in Code Canyon that you can purchase and set up a site like Coinmarketcap, but people trust sites that they always use daily, one of the features that you can add is adding a subscription pop up with freebies so they opt to subscribe, and when they subscribe you can give them fresh news and signal about the price of each coin in the market.
