Running the following command on the latest develop (same version than you'rs) works fine for me (without having a config.json !).

freqtrade download-data --exchange gemini --pairs BTC/USD LTC/USD BCH/USD ETH/USD -t 1h --days 5

One hint / suggestion when testing or working with multiple exchanges:
always make sure to not have a config.json in your current folder - but pass in a config.json explicitly if needed.

In your case, freqtrade loads config.json (including a pairlist) - and fails while validating the pairlist since gemini returns an unexpected result for markets.

You could fix that by removing pair_whitelist from the configuration ... but it's better to rename config.json - especially since i know that you're working with different exchanges often.

I've fixed that now in #2717 - but fixing the error will then result in errors because coins in config.json's whitelist are not available in the exchange (which is tracked as #2679).

I was using a gemini.json file and not a config.json @xmatthias

@Dante2333
a fix (#2717 ) was merged into the develop branch yesterday, pls update the bot and verify the solution.
