Where do you source your data for coin prices and market capitalizations?
Bitgur is the first-tier data provider. We use exchanges API directly.
Price on Bitgur differs from one of the competitors.
It's a normal situation because all data providers like bitgur have own set of exchanges, settings, and algorithms. So aggregated price differs a little on all price index sites. To monitor this we created a small project: Hodlzilla
. You can compare the price of any coin with four popular data providers.
