BestChange
recommended: observeBestChange is the web crawler bot that continuously monitors exchange rates from hundreds of cryptocurrency and e-currency exchangers, updating rate information every 5-8 seconds to provide real-time comparison data for crypto, fiat, and digital currency exchanges.
What it does
BestChange usually makes a single request within seconds of a URL being shared, without crawling further. Traffic rises and falls with sharing activity, so a widely circulated link can produce a sharp burst of fetches.
