Issues

Initially updating the rates from CoinApi without the ratesRefresher function that has a timeout to delay the concurrency throws: 'You exceeded Concurrency limit (number of maximum allowed concurrent requests per APIKey) for your subscription. Information about the current limit values can be found in the response headers included in this response, named X-ConcurrencyLimit-*. More information about this constraint can be found in the product documentation. Please reduce concurrency/threads or talk to the support about the upgrade'
