Now it's very much a coin that is already useful but left by the developer because there is no fund to back up the price or there is no clear cash flow from the coin or the basic concept of the coin is made failed. maybe a coin that can be useful at this time is what really can be used in real life and or coins that are supported by large companies such google or facebook . it sounds like there's no coin will be like that, but one day it can happen.
