I was curious about the original report since Bloomberg brings only the summons and I find this :
Total user accounts at service providers now exceed 139 million with at least 35 million identity-verified users, the latter growing nearly 4X in 2017 and doubling again in the first three quarters of 2018. Only 38 per cent of all users can be considered active, although definitions and criteria of activity levels vary significantly across service providers.
It means new users just sign up and do nothing, or maybe they buy very small amounts of coins which does not affect the global crypto market. I'm not sure this period could end for a few months, we are witnessing the beginning of each year is generally the worst period for cryptocurrency in terms of price.
This report also shows that only 38% of users are active, which would mean that roughly 60% of users do nothing except hold, and wait some better times.
