Interesting article and I am actually mostly interested in the crypto currencies you mentioned such as iota EOS and of course steemit. I still think However that at the moment by far the most interesting cryptocurrency is steemit, the steemit social network has already created a stable market place for the currency insuring demand. The usability of steemit is also the most mature I would say. Of course for hard core speculation you might not see the kinds of payoff in steemit as in some other cryptos. But then on the other hand some other cryptos might crash and burn and you loose it all. Steemit is more stable and with each new member and each new post we get stronger so in the long run I am sure that steemit will be a good investment l, not only for making money but for learning From other while in the same time learning also from yourself . Great article !
