Actually the word coward doesn't work in the field of economy. Here everyone is running for making some profit, and to make profit we need to be a bit coward for some time.
Being coward doesnt mean youre losing faith or what but most of the times, you used your brain and made wise decision before commiting such act but I could say there are users who are beyond coward in the field of bitcoin while wanting to earn faster and easier way which cannot be done in bitcoin.
