You are running this site for free right? You might wanna advertise your site(sharing job or whatsoever strategies) if you feel it is ready to gain more users. With good traffic, you can lease advertisement space in it for extra income Wink . Or try to develop an app and submit it to app stores for money
thats all is for future, I dont have enought traffic yet, I think about developing app for Android first and after for IOS, its depends if this project on web becomes successfully
And about the features, please consider on adding a row or column where you can put your buy price in that coin and it will automatically show your gains and losses in percentage.
Anyways, nice job! Good luck and more powers!
thanks for advice, I already add buy rate.
