Does anyone else believe in a great future for NEM (XEM) project? What event/new can affect the attraction of new investors?
Sadly there is no future, only pump&dump schemes. This sentence is valid for all cryptos including Bitcoin. All this is created to transfer wealth from small players to the big fishes. Some small fishes can only try to get in and get out in proper moments of this drama but at cost of 95% all other players. So is the way how it works imho.
You don't see that in the future some crypto coin can be used instead of Visa and such?
Before that the crypto value must be stabilized, ie. it should not change more than 1 % in a day
That stabilization happens when there is a common conception of the values.
Now there is not such yet. For example, BTC's value is 40 000 USD or 140 000 USD or 500 000 - - - depending on who you ask
