Title: Coinmarketcap and cryptmarketcap blow *you-know-what*
Post by: abel1337 on April 20, 2014, 06:15:15 PM
When I go to those sites I see that they display significantly different data in terms of the market caps of the coins. The price is usually accurate, but the market cap numbers are WAY off and I think this can be a problem to a bunch of people for obvious reasons.

I was looking to where the two sites get there data from and it appears they both get their numbers from the same source. Also the percentages are way off if you track the prices manually day-to-day. The source is cryptocoincharts. Since they are both getting their data from the same place, I can only conclude one of two things. Either:

  • They are getting their numbers at different times
  • Or they calculate them differently

If they are calculated differently, how is this so and why? Shouldn't there just be one solid call back function to display the most current marketcap for the top 200 or all of them if we wanted to from GitHub information? I am still new to programming but I wanted to try and solve this problem so more people could make better decisions in their trading. Thanks.

You are correct. This is an old scam. A coin makes their own exchange and trades with themselves creating fake volume and artificially inflating the price. An index based system might stifle this to a degree.

How might I go about starting this? I gave a little time to dedicate to this and I know a small amount of programming. pm me maybe we can make something happen
