MA periods question

[psycodad]

Hi,

I am trying to learn a bit about technical analysis and am currently looking at recognizing trends from moving average. I have read that in traditional stock and forex markets people often look at 5-day versus 20-day MA (and quite a few other combinations like 10/30, 50/200 etc.). I was wondering what MA timespans/periods people use in cryptocurrency markets to spot trends or trend changes?

Thanks in advance for any suggestions and tips.
