Bitcoin behaves more like a stock and not like a fiat currency - it is not suitable for trade and commerce.
In general the bitcoin owners belong to the ‘buy & hold’ investors or to the active traders groups.
There may be transactions for payment for goods / services but currently a small fraction compared with the 2 big groups.
I am not sure if the report also takes into account lightning network protocol transactions - they are not recorded on the main bitcoin blockchain.
