Hello Franklin,
In your code, the history request is requesting only 360 minutes of data, ending at the time you submitted the history request. Since there is about a 1 day delay for us to process and get crypto data up to date, no results are being returned since the data isn't there yet.
I would suggest using a date range when making a history request in research. For example: qb.History(qb.Securities.Keys, datetime(2020, 1, 1), datetime(2020, 1, 31), Resolution.Minute) - would get minute data history between 2020-01-01 and 2020-01-31.
Closing the issue as resolved since the expected data is in place.
Best,
Gerardo
