Uncertainty, because now e-money is dropping sharply, many people give up on them because of losses, no profit so I think in the future it may be difficult for electronic money to grow and It is not likely to be a major coin in this market.
We have seen things getting changed in matter of minutes and in crypto currency market, they do change so. Even a rise in the value of BTC can cause the rise in the inflow of investment funds into the altcoin category so I believe that people are still passionate about this area of earning.
