I feel airdrops are more like easy money and no predictions can be done on their price part. Still i see many of the organisations give free coins for publicity and we do not know whats the impact would be when their ICO is launched. Direction of price is not decided , hence the price direction may go anywhere and some give good rewards and some dont . Its simple as that its pure luck what my analysis says.
As of now, i see the best exchanges as of today are Etherdelta , YObit, Bittrex and CRyptopia. I see most of the traders and buyers/sellers use bittrex mostly for its user friendly interface and faster transaction rollout. Etherdelta is also good and can be seen in the second list. Exchanges have got to play important role in the crypto space as lost of transactions are happening day by day and we need many more facilities in the coming days on the exchanges.
ICO's only succeed if they have good ideas, good products and long term plans.Most of the ICO's i see, they do for obtaining funds and later on we do not know their whereabouts. But there are many ICO's who wants to invest long term and make a business model for better growth and performance. Still , i see after the ICO's as well, price rises only if there is demand and vice versa. Nobody can predict the ICO's softcap or hardcap and still it may go in nay direction.
I put it this way. As long as new products based business ideas are cropping up ICO's will never end. I see many scams as well but we have to see what a real product gives the benefits to its investors as well. I also see from longer point of view, crypto space is going to be used vastly and most of the traders, customers , sellers have to migrate slowly and this may happen in the future. So still i would say ICO will be cropping as long as new ideas are there in the market.
