Are you practicing your HTML/JavaScript lessons? Your website looks pathetic and you shouldn't be revealing it to the public at this stage. I'm glad you are open to suggestions but the interface is hideous. It will only make people go away from your site and never come back.
I agree with Joel, your website needs improvement though you are creating a very helpful free crypto portfolio. I logged in with that free demo and you really have to fix your front-end, after logging in those list of coins below is quite good and the chart above I think its need to be re-align.
