its like anything else the more people that use it the bigger the market becomes of it. Hence that free giveaway. They need people to start using it so it becomes real. There's some major apps out there like net cents that only allows you to buy with crypto the same things you would by with cash. Csc about to be added to that too. They have like 40 million outlets already accepting crypto.
But as HH its supposed to be safer and faster and cheaper for transactions hence its appeal.
