snipped...
I am not looking for a chart. I am looking for something similar to this site:
https://coinmarketcap.com/all/views/all/You can see the % change for all currencies in the last three columns. I am looking for this but in the 15 minute time frame.
I've looked at this too but I can find nothing. It is probably only the CMC that has a record of this. We have this alternative way to see and buy looking into a certain exchanger but expect the price is quite different from the other.
