I actually do not think so. All cryptos have been blown up by investors who just wanted to make lot of money. This "bubble" has bursted "a little" lately and therefore the prices have declined.
A lot of coins that do not provide any additional value other than "being crypto" will fail sooner or later. Gridcoin is different in this regard, as it does provide value for examples to researchers who want to buy computational resources. This allows gridcoin to build up value outside of the sheer speculation of people who just want to make fast gains.
