So is it not fair to consider ‘Copy Trading’ to also be a form of Social Trading? Albeit a modern day form of capitalist socialism 
Apparently eToro allows this sort of ‘communal’ activity, as exemplified by a Brit crypto currency trader here.
He seems to be doing alright with a $230,000 annual commission from his 9,143 follower’s/copier’s invested assets - not too sure how his community is faring though!
