Want free cryptocurrency? 'Airdrops' is coming...

In an "airdrop," makers of a new digital token give it out for free to some owners of existing coins.
"In certain ways people are getting free lottery tickets," says Matthew Roszak, co-founder of Bloq.
William Mougayar, blockchain investor, says airdrops are being misused. "Sadly, airdrops are the new spam mail or coupons junk mail."
