I made a free online tool to monitor the cryptocurrencies with the highest gains

Just finished developing this tool https://cryptodeltas.sciusanalytics.com/ where you can compare the gains of the top 200 cryptocurrencies (by marketcap) by different timeframes. It updates twice a day. I hope it's useful and let me know case you've got improvement suggestions. I've got some free time on my hands right now, so also tell me case you've got further ideas of related stuff you'd like to have.
