if you sign up you can add
coins to your favorite list to see all time on home screen and not to search every time what is current status
you can add your coins and amount of coins you have to monitor price
you can see summary price of all your coins


and many more for future
You should decide what it is you want to do with your project. Are you for monitoring assets? Are you an exchange? A trading bot creator?
I dont know yet, Im do this for myself depends on my need.
I like your site, the idea is to monitor 'my coins', right?
In that case, I have to sign up and fill the amounts all of my coins, and watch it grow or fall.
Nicely done, I will test it.
