People choose CryptoCurrency for diverse reasons.
I for one find crypto currency innovative. There are new ares of crypto that are profitable. It gives out more returns than other part. There trading, bounties, Airdrops and now recently, ICO, which did turn out to be very profitable before scams and the bear market came along.
crypricurrency is a great additional income or if you just want to develop your skills in differetn areas you can choose it
