Where do you get your Bitcoin and altcoin pricing from?

Prices are derived from the buy and sell volume of our clients who are trading on the platform. In addition to this, to provide the deepest liquidity at the common spot market price we utilize exchange liquidity when trade volumes exceed the available volume at Evolve.  In order to deal with a changing market, API reliability, maintenance, off-market pricing, etc. we utilize exchange liquidity from the exchange providing the best liquidity and reliability at the time. Depending on exchange market and technical conditions, we are using the following exchanges at any given time in the order of priority: Bitmex Swap, Bitstamp, Bitfinex, and Coinbase Pro
