But the ability to cut out the bullshit about not being able to make every member of your social network a merchant with no approval process needed, no more arbitrary holdbacks and requests for emailing scans of government id + utility bill, no more excluding the third world clients because they have bank secrecy laws which prevent the G7 from knowing where all the money goes, etc. An 0 transaction fee altcoin will do this.
