The real problem is decline in the prices of every token came from two sides. First they lost significant and more value in fiat because of the changes in price of Bitcoin and second little bit they lost against BTC as well. This is clearly visible everywhere also little input was from panicked dumpers but these markets have to stay here and grow again. Selling at low is loss else in future these will recover.
Because who will believe that you can use very volatile coins in shopping or other way of payments? Even bitcoin and the other top coins are still branded very volatile by regular world traders. The only thing the team needs to do is continue to develop a good platform because one day crypto currencies will become big and once it reaches in trillions value then volatility loosens.
